Effect of depression combined with cognitive impairment on dependency risk in rural older adults: analysis of data from the China health and retirement longitudinal study (CHARLS 2020).
Article in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThis study aims to investigate the relationship between cognitive impairment, depressive symptoms, and Activities of Daily Living (ADL)/ Instrumental Activities of Daily Living (IADL) dependency among older people living in rural areas.
methodsWe analyzed data from the China Health and Aging Longitudinal Study 2020, focusing on the rural older adults over 60. We identified four groups and constructed three regression models (models 1-3) to investigate the relationship between cognitive impairment or depression and dependency.
resultsBased on a logistic regression model, older adults living in rural areas face a sequentially increased risk of dependence on ADL if they in group 2 (OR = 1.33, 95% CI = 1.09-1.63), group 3 (OR = 1.76, 95% CI = 1.43-2.17), or group 4 (OR = 2.38, 95% CI = 1.95-2.91), when compared to a reference group 1. Group 2 (OR = 2.44, 95% CI = 2.03 to 2.93) was more likely to be at risk of IADL dependence than Group 3 (OR = 1.99, 95% CI = 1.64 to 2.43).
conclusionsThis study highlights the substantial impact of depression and cognitive impairment on ADL/IADL dependence among rural older adults, with an especially heightened risk when both disorders are present simultaneously. Moreover, factors such as gender, age, inpatient services, outpatient services, and self-rated health are strongly associated with functional dependence in this population.
