Depressive symptoms and association with prevalent cardiovascular disease: A cross-sectional analysis in Port-au-Prince, Haiti.
Article in PLOS mental health, 2026. 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
Cardiovascular disease (CVD) is the leading cause of mortality in low- and middle-income countries, and depression remains an underexplored CVD risk factor in Haiti. We assessed the association between depressive symptoms (DS) and prevalent CVD in urban Haiti and examined sex differences using a cross-sectional analysis of enrollment data from the Haiti Cardiovascular Disease Cohort (adults ≥18 years; March 2019-August 2021). DS were measured using the Patient Health Questionnaire-9 and categorized as none-mild (<10) versus moderate-severe (≥10). Prevalent CVD (angina, myocardial infarction, transient ischemic attack or stroke and heart failure) was adjudicated using epidemiologic definitions aligned with international cohorts. Prevalence ratios (PRs) were estimated using generalized estimating equation Poisson models with a log link, adjusting for age, sex, education, income, food insecurity, smoking, alcohol use, physical activity, stress, and ody Mass Index; effect modification by sex was assessed on multiplicative and additive scales. Among 2,995 participants (mean age 41.9 years; 58.0% female), 16.2% had moderate-severe DS, with higher prevalence in females (22.0%) than males (8.5%). CVD prevalence was higher among those with moderate-severe DS than none-mild DS in both sexes (males: 21.5% vs. 10.6%; females: 23.3% vs. 15.3%). Moderate-severe DS were independently associated with higher CVD prevalence (adjusted PR = 1.36; 95% CI: 1.08-1.71). Sex-stratified estimates were 1.38 (95% CI: 1.06-1.78) for females and 1.25 (95% CI: 0.75-1.99) for males; evidence for additive interaction by sex was limited (RERI = 0.07, 95% CI: -0.74 to 0.88). DS were independently associated with higher CVD prevalence in urban Haiti, with a consistently stronger pattern among women, although formal tests of effect modification was not statistically significant. Integrating depression screening into CVD prevention may help address the growing burden of both conditions in resource-limited settings. Prospective studies are needed to clarify the underlying mechanisms and causal pathways.
