Depression and risk of hospital readmission in older patients with heart failure: a systematic review and meta-analysis.
Review in Frontiers in cardiovascular medicine, 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
Background: Depression is common among patients with heart failure (HF) and may adversely affect clinical outcomes. However, its association with hospital readmission in older patients with HF remains incompletely understood. Methods: A systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. PubMed, Embase, Web of Science, CNKI, and Wanfang databases were searched from inception to 31 December 2025. Cohort studies examining the association between depression and readmission outcomes in patients with HF were included. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Results: A total of 29 studies were included, of which 13 were eligible for meta-analysis. Depression was associated with a significantly increased risk of readmission and adverse outcomes (HR = 1.76, 95% CI: 1.30-2.40). In studies using continuous measures, higher depressive symptom scores were also associated with increased risk (HR = 1.04, 95% CI: 1.02-1.07). Subgroup analyses suggested a stronger association in studies with longer follow-up, although between-group differences were not statistically significant. Sensitivity analyses confirmed the robustness of the findings. Conclusions: Depression is associated with an increased risk of readmission in patients with heart failure. Routine assessment of depressive symptoms may improve risk stratification and support targeted post-discharge management, particularly in older populations.
