Dose-response relationship between nighttime sleep duration and intrinsic capacity declines among Chinese elderly: a cross-sectional study from CHARLS.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
backgroundIntrinsic capacity is a crucial indicator of adverse outcomes and has predictive value for diseases and mortality. The objective of this study is to assess the association between nighttime sleep duration and intrinsic capacity in older Chinese adults.
methodsData were collected from the China Health and Retirement Longitudinal Study (CHARLS) spanning the years 2008-2020. Minimally sufficient adjustment was made for confounding factors identified through a Directed Acyclic Graphs (DAGs), and multivariate logistic regression analysis was conducted to determine the relationship between nighttime sleep duration and intrinsic capacity. Restricted cubic splines (RCS) were used to assess the nonlinear relationship between nighttime sleep duration and intrinsic capacity in this population. Finally, subgroup analysis and interaction effect analysis were performed.
resultsAmong the 4994 older adults, 3118 (62.4%) experienced a decline in intrinsic capacity. After adjusting for confounding factors, nighttime sleep duration was associated with an increased risk of intrinsic capacity decline (P < 0.001), exhibiting a nonlinear J-shaped pattern.
conclusionsFor Chinese older adults, increased nighttime sleep duration shows a nonlinear, J-shaped dose-response relationship with the risk of intrinsic capacity decline. Our study provides important insights into the intrinsic capacity and health self-management of older adults.
