Socioeconomic disparities in the prevalence of non-communicable chronic disease multimorbidity and their impact on activities of daily living among older adults in rural southwest China: a cross-sectional study.
Article in BMC geriatrics, 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
backgroundThis study investigates socioeconomic disparities in the prevalence of five non-communicable chronic diseases (NCDs) - hypertension, diabetes, coronary heart disease (CHD), stroke, and chronic obstructive pulmonary disease (COPD) - and their multimorbidity, and examines the relationship between NCDs multimorbidity and activities of daily living (ADL) among older adults in rural southwest China.
methodsA cross-sectional health interview and survey of 5,548 consenting adults aged ≥ 60 years was conducted. An individual socioeconomic position (SEP) index was constructed using principal component analysis. Anthropometric measurements, blood pressure, fasting blood glucose, and post-bronchodilator spirometry tests were recorded for each participant. ADL was evaluated using the Lawton scale.
resultsThe overall prevalence of hypertension, diabetes, CHD, stroke, COPD, and their multimorbidity was 65.8%, 13.7%, 8.5%, 5.9%, 7.3%, and 22.8%, respectively. Participants with a lower education level had a higher prevalence of hypertension than their counterparts (P < 0.01), while participants with better access to medical services had a higher prevalence of diabetes than their counterparts (P < 0.05). Individuals with higher annual household income and SEP had a higher prevalence of diabetes, COPD, and NCDs multimorbidity than their counterparts (P < 0.01). Multivariable binary logistic regression analysis revealed that individuals with NCDs multimorbidity had a greater probability of impairments in ADL, physical activities of daily living (PADL), and instrumental activities of daily living (IADL) (OR = 1.27, OR = 1.28, and OR = 1.79, respectively, all P < 0.01).
conclusionsSocioeconomic disparities are significantly associated with the prevalence of NCDs and their multimorbidity among older adults in rural southwest China. Multimorbidity is linked to a higher likelihood of functional limitations in ADL. This research uncovers the need to improve ADL among older adults with NCDs multimorbidity.
