Associations between modifiable risk factors and limitation in activities of daily living among individuals aged ≥ 45 years: Evidence from the China health and retirement longitudinal study (CHARLS).

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
Background: With aging populations, a growing number of older people are subjected to limitations in activities of daily living (ADL), causing a tremendous burden and challenges to patients' quality of life and policymakers. Investigating modifiable risk factors for ADL remains an important project to help lower its risk. This study aimed to explore associations between the modifiable risk factors and ADL using national-scale data from the China Health and Retirement Longitudinal Study (CHARLS). Methods: Data were downloaded from CHARLS 2020, a population-based longitudinal survey. We included modifiable risk variables and ADL index, i.e., basic ADL (BALD) and instrumental ADL (IADL). Afterward, variables were included in the logistic regression model construction. Also, propensity score matching (PSM) was employed to validate the findings. Finally, we tried to discuss the associations between different age groups. Results: A total of 12,248 participants were included in this study, comprising 5799 women (47.35%) and 6449 men (52.65%). The median age was 62 (55-69) years. Among the participants, 2055 (16.78%) had limitations in BADL, and 1838 (15.01%) had limitations in IADL. Logistic regression demonstrated that exercise significantly reduced the risk of BADL and IADL impairment (BADL: Conclusions: Modifiable risk factors, such as exercise, cognitive ability, depression symptoms, chronic diseases, social activities, and sleeping duration, were significantly associated with ADL. Besides, as age increases, the impact of various modifiable risk factors on ADL becomes more evident, emphasizing special care for older populations and offering scientific ideas for policymakers.
