However, due to the presence of confounders, some outcome measures were excluded from the analysis, e.g., inflammation parameters when acute infection symptoms were reported in the monitoring questionnaire administered at timepoint t3 or V2 (n = 6); depression, anxiety and stress score, or QoL measures when severe stressful life events or a fundamental change in life conditions were reported during V2 assessment (n = 4); and weight and waist circumference when supplementation of thyroid hormones was introduced (n = 1). This evidence concerns the gene TG and major depressive disorder.
