Spousal concordance and interdependence in depression among older adults: A cross-cultural longitudinal study in China, the United States, and England.
Article in Psychological 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
backgroundLate-life depression often extends to the marital partner, yet mechanisms of dyadic interdependence and their cross-cultural generalizability remain unclear.
methodsWe analyzed harmonized longitudinal data from couples in the China Health and Retirement Longitudinal Study (CHARLS;
resultsWithin-couple correlations of depressive symptoms were positive in every cohort (
conclusionsConcordance in late-life depressive symptoms replicates across three major aging cohorts; in CHARLS, it primarily reflects stable between-couple similarity, whereas modest within-person prospective coupling persists in ELSA and in the multiple-imputation HRS estimates. Bidirectional depression-disability coupling in Western cohorts is the most replicable within-person signal, supporting combined depression management and functional rehabilitation for older couples.
