Longitudinal Associations of Cumulative Depression Burden With Cardiovascular Diseases and All-Cause Death Among Middle-Aged and Older Population: Evidence From 2 Nationwide Cohort Studies.
Article in Journal of the American Heart Association, 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
backgroundDepression is a known risk factor for cardiovascular disease (CVD), but the impact of long-term depressive symptom burden remains unclear. We examined the association between cumulative depression burden and risks of CVD and all-cause death among adults aged ≥50 years in China and Mexico.
methodsData were obtained from 2 nationally representative cohorts: CHARLS (China Health and Retirement Longitudinal Study) and MHAS (Mexican Health and Aging Study). Cumulative depression burden was quantified using 2 approaches: (1) the area under the curve of repeated depression scores and (2) the number of waves with depression. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs for incident CVD and all-cause death.
resultsThe analysis included 5277 CVD-free participants from CHARLS and 4779 from MHAS. Higher cumulative depression burden was significantly associated with elevated risk of CVD. Compared with the lowest-quartile group, participants in the highest-quartile group had significantly greater CVD risk (CHARLS: HR, 1.723 [95% CI, 1.420-2.090]; MHAS: HR, 1.739 [95% CI, 1.347-2.245]). Dose-response associations were observed in both cohorts. Persistent depression was also linked to higher CVD risk compared with isolated or less frequent episodes. Associations with all-cause death differed by cohort, with significant associations observed in CHARLS but not in MHAS.
conclusionsLong-term cumulative depression burden is strongly associated with increased CVD risk among adults aged ≥50 years. Routine screening and sustained management of depressive symptoms should be considered integral to CVD prevention strategies.
