In a community-based cohort study, 154,549 postmenopausal women without dementia at enrolment (between 2006 and 2010) from the UK Biobank were followed up until June 2021. Age at menopause (<40, 40-49, and =50 years) was used to predict the primary outcome of allcause dementia in a time-to-event analysis. In total, 2266 incident cases of dementia were observed over a median follow-up period of 12.3 years. After adjusting for confounders, women with earlier menopause showed a higher risk of all-cause dementia compared with those ≥50 years (adjusted-HRs [95% CIs]: 1.21 [1.09-1.34] and 1.71 [1.38-2.11] in the 40-49 years and <40 years groups, respectively; P for trend <0.001). Which of the following is an accurate interpretation of the reported results?
What type of graph will estimate the probability of survival over time?
A recent mediation analysis study examined the direct effect of clozapine on the dopaminergic pathways related to motivation and pleasure in patients with treatment-resistant schizophrenia. The study aimed to determine whether clozapine’s impact on negative symptoms, such as avolition and anhedonia, could be partially attributed to its modulation of the mesolimbic dopamine system. Which of the following findings would most likely support the hypothesis that clozapine directly improves motivation and pleasure by acting on this pathway?
In considering the clinical use of clozapine for the management of treatment-resistant schizophrenia, the medication’s profile must be carefully weighed against potential side effects. One significant concern is the risk of clozapine-induced sedation, which can exacerbate symptoms of low motivation commonly observed in schizophrenia. What is the primary reason clozapine should be used cautiously or avoided in patients with preexisting low motivation?
A screening instrument has a pre-test probability of 1 in 8 with 80% sensitivity and 80% specificity. Calculate the post-test odds of a positive test result.
A researcher spends one month collecting the published news from all British tabloids since the Covid pandemic started that contained the term “mental health” and analyses the patterns of reporting. What is the appropriate term to describe this type of research?
A research team is evaluating the performance of a newly developed diagnostic test for psychotic relapse in established schizophrenia using speech samples. The prevalence of relapses per year)in the observed population is estimated to be 37% of individuals. The researchers recruit a sample of 1,000 individuals, all of whom are at a higher risk of relapse due to recent discontinuation of their treatment. The initial sensitivity of the new speech-based test is found to be 80%. This means that out of those individuals who have relapse, the test correctly identifies 80% as relapsed. However, the specificity of the test is very high, indicating that it accurately identifies individuals without relapse as negative. Using the collected data, the research team wants to assess how an increase in sensitivity of the speech test might impact various statistical measures, including Positive Predictive Value (PPV), Negative Predictive Value (NPV), and statistical power of studies that employ this speech test to select patients that are relapsing. They plan to use a machine learning approach that increases the sensitivity of their test notably, increasing the test’s clinical utility and its potential to detect relapse more effectively. When the sensitivity of a test increases…

In which of the following scenarios is it more appropriate to use the McNemar test instead of the chi-square test?
In a longitudinal study assessing the progression of amnestic mild cognitive impairment (MCI) in older adults, subjects were randomized to receive either lithium or a placebo. Over the study period, clinical assessments were conducted to evaluate the therapeutic impact of lithium on cognitive stability and conversion to dementia. Based on the neuroprotective properties of lithium, which of the following outcomes would most likely be observed in the lithium-treated group compared to the placebo group?
A Kaplan-Meier survival analysis was employed in a clinical study to compare the progression of amnestic mild cognitive impairment (MCI) to dementia in older adults treated with lithium versus a placebo. The survival curve was used to illustrate the probability of remaining free from dementia over time. If the Kaplan-Meier curve for the lithium group shows a slower decline towards the endpoint of dementia compared to the placebo group, what could be inferred about the efficacy of lithium based on this analysis?
In a clinical study assessing the long-term effects of lithium in patients with amnestic mild cognitive impairment (MCI), researchers conducted a Kaplan-Meier survival analysis to determine the rate of conversion to dementia. The study found that the lithium-treated group had a marginally statistically significant reduction in the risk of conversion to dementia over the placebo group. What does the term “marginal statistical significance” imply about the study’s findings regarding lithium treatment?
In a Kaplan-Meier survival analysis, a chi-square test has been conducted with degree of freedom being 1. What does this degree of freedom represent?
Low physical activity and sedentary behaviour significantly impact the mental health and overall health of individuals with schizophrenia. A research study [Pieters LE, et al. Schizophrenia Bulletin. 2021 Jul 1;47(4):906-14] explored the connection between movement disorders (akathisia, dyskinesia, dystonia, and parkinsonism) and physical activity in 216 schizophrenia patients. Adult patients who lived at long-term mental healthcare units for more than 1 year or sheltered housing facilities of a mental health care institution were included, if they had at least 3 days of actigraphy data for 6hrs/day and validated measures of extrapyramidal symptoms and psychopathology at the same time. To investigate the statistical relationship between movement disorders and actigraphy data the authors performed multiple linear regression analysis. Parkinsonism was significantly associated with decreased physical activity (β = -0.21, P < .01) and increased sedentary behaviour (β = 0.26, P < .001). For dystonia, only the relationship with sedentary behaviour was significant (β = 0.15, P < .05). Akathisia was associated with more physical activity (β = 0.14, P < .05) and less sedentary behaviour (β = -0.15, P < .05). For dyskinesia, the relationships were nonsignificant. In a prediction model, akathisia, dystonia, parkinsonism and age significantly predicted physical activity (F(5,209) = 16.6, P < .001, R-squared adjusted = 0.27) and sedentary behaviour (F(4,210) = 13.4, P < .001, R-squared adjusted = 0.19). What is the most likely study design employed here?

A cross-sectional study examined the relationship between dietary fiber intake and mental health in a large population of adults, using a cross-sectional study among 3,362 Iranian adults working in 50 health centers. After adjustment for potential confounders, participants in the top quartile of total dietary fiber intake had a 33% and 29% lower risk of anxiety and high psychological distress [odds ratio (OR): 0.67; 95% CI: 0.48, 0.95 and OR: 0.71; 95% CI: 0.53, 0.94, respectively] compared to the bottom quartile of intake. The highest total dietary fiber intake was also inversely related to a lower risk of depression in women (OR: 0.63; 95% CI: 0.45, 0.88) but not in men. Among overweight or obese participants, higher intake of dietary fiber was related to a decreased risk of high psychological distress (OR: 0.52; 95% CI: 0.34, 0.79). A high level of dietary fiber intake was related to a lower risk of anxiety in normal-weight individuals (OR: 0.50; 95% CI: 0.31, 0.80). These results highlight the presence of significant inverse associations between total dietary fiber intake with anxiety and high psychological distress. What is the single most important factor that will enable you to establish a causal factor between the dietary fiber and psychiatric outcomes?
Long-term use of antipsychotics that increase prolactin levels is associated with an elevated risk of breast cancer. After a review of longitudinal studies over a 5-year period, researchers found that certain antipsychotics with high prolactin-elevating potential contribute to this risk. Which of the following mechanisms most likely explains why antipsychotics that elevate prolactin levels are linked to an increased risk of breast cancer?
A 2021 study examined Finland’s health databases to investigate the association between prolactin increasing antipsychotic use in women with schizophrenia and breast cancer risk, while considering established risk factors. Using a case-control design within a patient cohort, the study included women diagnosed with schizophrenia or schizoaffective disorder between 1972 and 2014. “Cases” were those diagnosed with breast cancer from 2000 to 2017, matched with “controls” without breast cancer in this patient cohort. Both groups had a history of inpatient mental health care, and matching considered age and time since schizophrenia diagnosis. 1,069 women were identified as breast cancer cases and matched with 5,339 controls. In the context of the information presented here, which of the following descriptions captures the 5,339 individuals defined as “controls”?
In epidemiological studies, researchers often use statistical methods to estimate the relationship between an exposure and an outcome. When studying the association between smoking and lung cancer, researchers calculated both adjusted and unadjusted odds ratios (ORs). If the unadjusted OR was 2.5 and the adjusted OR, after controlling for age, sex, and occupational exposure to carcinogens, was 1.8, what does the difference between these odds ratios suggest about the relationship between smoking and lung cancer?
A research study based on the QResearch primary care database used by UK general practices aimed to investigate associations between different antidepressant treatments and the incidence of three cardiovascular outcomes (myocardial infarction, stroke or transient ischaemic attack, and arrhythmia) in individuals diagnosed with depression. The study included 238,963 patients aged 20 to 64 years with an initial diagnosis of depression between January 1, 2000, and July 31, 2011. The research assessed various factors, including antidepressant class, dose, duration of use, and individual antidepressant drugs. Cox proportional hazards models were used to estimate hazard ratios while adjusting for potential confounding variables. The results indicated that there were no significant associations between antidepressant class and myocardial infarction over five years of follow-up. However, during the first year of follow up, patients treated with selective serotonin reuptake inhibitors had a significantly reduced risk of myocardial infarction (adjusted hazard ratio 0.58, 95% confidence interval 0.42 to 0.79) compared with no use of antidepressants, particularly fluoxetine (0.44, 0.27 to 0.72). Lofepramine, on the other hand, was associated with an increased risk (3.07, 1.50 to 6.26). No significant associations were found between antidepressant class or individual drugs and the risk of stroke or transient ischaemic attack. Antidepressant class was not significantly associated with arrhythmia, although there was an increased risk during the first 28 days of treatment with tricyclic and related antidepressants (adjusted hazard ratio 1.99, 1.27 to 3.13). Fluoxetine was associated with a reduced risk of arrhythmia over five years (0.74, 0.59 to 0.92), while citalopram was not significantly associated with arrhythmia risk, even at high doses (1.11, 0.72 to 1.71 for doses =40 mg/day). What type of study design was employed in this research?

To understand the relationship between childhood traumatic experiences and the sensory complexity of hallucinations, a cohort of 75 children and adolescents seeking help for hallucinations were studied. To determine the extent by which the various sensory modalities could predict the probability of a previous early trauma, the authors employed a hierarchical binomial logistic regression with history of childhood trauma as the binary dependent variable with control variables (i.e., age, educational level and number of ICD-10 diagnoses, the presence of suicidal ideation), and the number of hallucinatory modalities as predictors. The number of hallucinatory modalities appeared to be the only significant predictor of childhood trauma (estimate (i.e. the log odds of ‘history of childhood trauma’ = 1 v. 0) 0.81, s.e. = 0.34, z = 2.39, P = 0.017, OR = 2.24 (95% CI 1.16–4.33).
