Association of sarcopenia and frailty with sleep quality trajectories in middle-aged and older Chinese adults: findings from a nationally representative cohort study.
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 3 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
backgroundFew studies have examined the associations of sarcopenia, frailty, and sleep quality (SQ) trajectories among middle-aged and older Chinese adults. Our aim was to investigate these relationships using a nationally representative longitudinal study.
methodsThe study utilized 2011-2015 data from the China Health and Retirement Longitudinal Study (CHARLS), focusing on individuals aged 45 years and above. Sarcopenia and frailty were assessed at baseline. SQ was evaluated biennially via interview-based assessments from 2011 to 2015, with SQ scores calculated accordingly. A group-based trajectory model was applied to analyze the aging trajectory of SQ over time, while multinomial logistic regression was used to examine the associations between sarcopenia and frailty with SQ trajectory membership.
resultsAmong 8,918 participants aged 45 years and older at baseline, trajectory analysis based on overall SQ scores identified four longitudinal patterns of SQ: "high sleep disorder trajectory" (n = 999, 11.20%), "moderate sleep disorder trajectory" (n = 3,714, 41.64%), "mild sleep disorder trajectory" (n = 2,197, 24.64%), and "low sleep disorder trajectory" (n = 2,008, 22.52%). After adjusting for demographic, behavioral, and health confounders, both sarcopenia and frailty were significantly and positively associated with mild, moderate, and high sleep disorder trajectories (all OR > 1, all 95% CI excluded 1, all P < 0.05).
conclusionThese findings suggested that sarcopenia and frailty were negatively associated with SQ trajectories.
