Chronic disease multimorbidity and mental health among older adults in China: The moderating roles of family and social support.
Article in PloS one, 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
Population aging has been accompanied by a growing prevalence of chronic disease multimorbidity among older adults, raising increasing concerns about its implications for mental health. Although previous studies have documented the negative association between multimorbidity and mental health, evidence regarding how support systems influence this relationship remains limited. Using nationally representative cross-sectional data from the 2020 China Longitudinal Aging Social Survey (CLASS), this study examined the association between self-reported multimorbidity and mental health among older adults in China, with particular attention to the moderating roles of family support and social support. Multivariate regression models incorporating interaction terms were employed to estimate both direct and interaction effects. The results indicate that, first, multimorbidity is significantly associated with poorer mental health among older adults. Second, although both social support and family support are positively associated with better mental health, only family support significantly moderates the association between multimorbidity and mental health. Third, marginal effects analysis shows that the negative association between multimorbidity and mental health becomes progressively stronger as the level of family support increases. Fourth, subgroup analysis reveals that the direct association between family support and mental health follows a U-shaped pattern across age groups, whereas its moderating effect on the relationship between multimorbidity and mental health gradually weakens with advancing age and becomes statistically insignificant among adults aged 80 years and above. These findings contribute to a more nuanced understanding of interpersonal resources in later life and highlight the need to integrate family-centered approaches into geriatric care and mental health interventions for older adults living with multimorbidity.
