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
backgroundAlthough low muscle strength is an important factor in poor clinical outcomes among older patients, information on its relationship with cognitive and physical function among hospitalized older adults is lacking. The aim of this study was to examine the association between handgrip strength (HGS) and cognitive and physical function among hospitalized older adult inpatients in Tanzania.
methodsThis multicentre cross-sectional study was conducted between March and August 2022 in the medical wards of four hospitals in Tanzania. Adults aged ≥ 60 years who were hospitalized were eligible; of 540 approached, 308 completed the full study assessment and were included in the analysis. Handgrip strength was measured with a handheld dynamometer and classified as normal or weak based on established cut-points. Physical function was assessed using the Barthel Index for activities of daily living, and cognitive function was assessed using the Identifying Dementia in Elderly Africans cognitive screen (IDEA-Cog). Logistic regression model was used to examine associations between handgrip strength (dependent variable) and cognitive and functional status.
resultsAmong the 308 patients assessed, weak handgrip strength was significantly associated with poorer cognitive performance (β = 0.454, OR = 1.58, 95% CI [. 235, 0.673], p = .001) and higher physical function (β = 0.304, OR = 1.36, 95% Cl [0.133, 0.474], p = .001). CONCLUSION AND IMPLICATIONS: Weak handgrip strength is associated with poorer cognitive performance and higher physical dependence among hospitalized older adults across settings. These findings support the potential use of HGS as a clinical marker to identify older adults with concurrent cognitive and functional vulnerability. Future longitudinal studies are warranted to examine this association over time.
