Evidence for causal effects of neuropsychiatric conditions on risk of venous thromboembolism: A univariable and multivariable Mendelian randomization study.
Review in Journal of vascular surgery. Venous and lymphatic disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSubstantial observational evidence suggests an association between neuropsychiatric conditions and venous thromboembolism (VTE). However, the causal relationship between these two conditions requires further investigation. Therefore, we used a two-sample Mendelian randomization (MR) approach to assess the bidirectional causal effects between four neuropsychiatric conditions and VTE, deep vein thrombosis, and pulmonary embolism (PE).
methodsGenetic variants associated with four neuropsychiatric conditions (ie, schizophrenia, major depressive disorder [MDD], bipolar disorder, and epilepsy) and VTE, deep vein thrombosis, and PE were selected. Bidirectional univariable and multivariable MR methods were applied to evaluate the causal relationships among these conditions. The primary causal estimates were obtained using the inverse variance weighted method with multiplicative random effects, supplemented by MR Egger regression, weighted median, simple mode, and weighted mode. Sensitivity analysis was conducted using the MR pleiotropy residual sum, funnel plots, and outlier (MR pleiotropy and residual sum and outlier) method.
resultsUnivariable MR results showed that genetic susceptibility to MDD increases the risk of VTE and PE (VTE: odds ratio [OR], 1.25; 95% confidence interval [CI], 1.08-1.46; P = .004; PE: OR, 1.36; 95% CI, 1.09-1.69; P = .006) and that PE has an adverse causal effect on MDD (OR, 1.02; 95% CI, 1.00-1.04; P = .026). Adjustment for confounders such as obesity, sleep duration, smoking, physical activity, and alcohol consumption revealed that increased genetic susceptibility to MDD is also associated with VTE and PE.
conclusionsOur results suggest that genetic susceptibility to MDD might have an adverse causal effect on the risk of VTE and PE and that PE has a reverse causal effect on MDD. Prevention and early diagnosis of depression are crucial in the management of VTE and PE.
