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
backgroundSarcopenia and frailty are interrelated complex geriatric syndromes that are associated with an increased risk of negative health outcomes. The construction of an age-friendly environment (AFE) is a key strategy for promoting health aging, but its associations with sarcopenia and frailty remain unclear. This study aimed to explore the association between AFE and the incidence of sarcopenia and frailty in older adults.
methodsA total of 3,261 participants aged ≥60 years were included from the China Health and Retirement Longitudinal Study (CHARLS). Using a World Health Organization (WHO) AFE framework modified for Chinese context, we constructed an 8-domain, 35-component community environment score. Sarcopenia was defined according to the 2019 consensus guidelines by the Asian Working Group for Sarcopenia, while frailty status was assessed using the frailty index (FI). The longitudinal association between AFE score and the risk of developing incident sarcopenia and frailty was evaluated using Cox proportional hazards regression models.
resultsOver a 4-year follow-up, 297 (9.10%) participants developed sarcopenia; and participants with sarcopenia had a higher FI. Compared to the lowest quartile of AFE scores, participants in the highest AFE quartile had a 46% lower risk of incident sarcopenia (HR: 0.54, 95% CI: 0.38-0.77) and a 27% lower risk of incident frailty (HR: 0.73, 95% CI: 0.60-0.90), even after comprehensive confounding adjustment. Subgroup analyses showed a significant interaction between independent ADL and AFE was observed for sarcopenia, while significant interactions by residence and health status were observed for frailty.
conclusionsOur findings underscore that constructing an age-friendly environment is of great significance for the prevention of incident sarcopenia and frailty among older adults in China.
