Prevalence of depression among rural older adults in Asia: a meta-analysis of observational studies.
Synthesis in Frontiers in public 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
Background: Despite the prevalence of depression among rural older adults in Asia having been widely investigated, existing estimates remain highly inconsistent. This meta-analysis of observational studies aimed to quantify the pooled prevalence of depression and determine potential moderating factors among rural older adults in Asia. Methods: A systematic literature search was performed in PubMed, Web of Science, Scopus, Embase, Cochrane Library, CINAHL, and PsycINFO from inception to May 2026. Pooled prevalence estimates were calculated using a random-effects model, with both 95% confidence intervals and 95% prediction intervals reported for each estimate. Heterogeneity was assessed using the I Results: A total of 68 studies comprising 58,577 rural older adults in Asia were included, yielding a pooled prevalence of depression of 34.6% (95% CI: 29.9-39.6%, 95% PI: 3.9-75.9%, Conclusions: Our findings indicate that depression is common among rural older adults in Asia. The pooled prevalence estimate exhibited substantial statistical heterogeneity and a wide prediction interval, only partly accounted for by covariates such as mean age, proportion of married participants, economic status, and geographic region. Therefore, caution is advised when interpreting this estimate in clinical practice. Furthermore, the substantial mental health burden in this population highlights the urgent need for routine screening and tailored interventions to reduce depression.
