Open AccessPolygenic scores for cardiovascular risk factors improve estimation of clinical outcomes in CCB treatment compared to pharmacogenetic variants alone
Pharmacogenetic variants are associated with clinical outcomes during Calcium Channel Blocker (CCB) treatment, yet whether the effects are modified by genetically predicted clinical risk factors is unknown. We...

Open AccessEffects of physical activity and sedentary time on depression, anxiety and well-being: a bidirectional Mendelian randomisation study
Mental health conditions represent one of the major groups of non-transmissible diseases. Physical activity (PA) and sedentary time (ST) have been shown to affect mental health outcomes in opposite directions....

Open AccessMendelian randomisation study of body composition and depression in people of East Asian ancestry highlights potential setting-specific causality
Extensive evidence links higher body mass index (BMI) to higher odds of depression in people of European ancestry. However, our understanding of the relationship across different settings and ancestries is lim...

Open AccessImpact of lack-of-benefit stop** rules on treatment effect estimates of two-arm multi-stage (TAMS) trials with time to event outcome
In 2011, Royston et al. described technical details of a two-arm, multi-stage (TAMS) design. The design enables a trial to be stopped part-way through recruitment if the accumulating data suggests a lack of benef...
