Sleep traits and physical activity mediate the causal association between depression and age-related diseases.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundA growing body of evidence suggests the relationship of depression with an increased risk of age-related diseases (ARDs). To further understand the genetically predicted causative connections, a Mendelian randomization (MR) approach was conducted.
methodsGenetic variants associated with depression were employed as instrumental variables from the PGC and FinnGen consortium, respectively. GWAS summary data for 14 ARDs were derived from recently large consortia. We employed univariable and bidirectional MR analysis, and meta-analysis combining the results from two databases. Importantly, the potential mediation effects and mediated proportions of sleep and exercise traits were evaluated using a two-step mediation MR analysis. Finally, the robustness of all the MR results was confirmed using multiple sensitivity analyses.
resultsIn univariable MR analysis, results of combine effect showed that genetically linked depression was causally associated with a range of ARDs, including myocardial infarction (MI) (OR: 1.156, 95%CI: 1.038-1.288, p = 0.008), coronary atherosclerosis (CAS) (OR: 1.008, 95%CI: 1.004-1.013, p < 0.001), peripheral arteriosclerotic disease (OR: 1.002, 95%CI: 1.000-1.003, p = 0.020), obesity (OR: 1.028, 95%CI: 1.001-1.056, p = 0.044), type 2 diabetes (T2D) (OR: 1.112, 95%CI: 1.034-1.197, p = 0.004), and metabolic syndrome (OR: 1.204, 95%CI: 1.064-1.364, p = 0.003). Reverse analyses revealed the causal effect of obesity on depression (OR: 1.110, 95%CI: 1.070-1.152, p < 0.001). In mediation analyses, physical activity and/or sleep traits mediated the causal associations between depression and MI, CAS, and T2D. We further quantified the mediation effects. Sensitivity analyses supported these observations.
conclusionDepression is causally associated with MI, CAS, peripheral arteriosclerotic disease, obesity, T2D, and metabolic syndrome. Moreover, physical activity and sleep traits, either individually or in combination, appear to mediate the causal associations.
