Delving Into the Nuances: Absolute Versus Relative Handgrip Strength for Probable Sarcopenia in Prediabetes.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 reflects a clinically relevant reduction in muscle strength and performance, contributing to adverse metabolic outcomes, including prediabetes. While absolute handgrip strength (HGS) is used in diagnostic criteria, relative HGS (RHGS) may better reflect functional muscle impairment, particularly in populations with variable adiposity. This study aimed to assess the prevalence of probable sarcopenia using absolute HGS and to evaluate the diagnostic performance of RHGS in identifying low HGS-defined probable sarcopenia among prediabetic adults.
methodsA cross-sectional study was conducted among 149 prediabetic adults aged 30-60 years at a tertiary care center. Absolute HGS was measured using a digital dynamometer following standardized protocols. Probable sarcopenia was identified using established Asian Working Group for Sarcopenia (AWGS) 2019 cutoff values. RHGS was calculated as HGS/body mass index (BMI). Receiver operating characteristic (ROC) analysis was performed to assess the discriminatory ability of RHGS in identifying low HGS-defined probable sarcopenia. Sociodemographic and biochemical parameters were also collected and analyzed using SPSS v23 (IBM Corp., Armonk, NY, USA).
resultsProbable sarcopenia was identified in 8% of the study population. RHGS was significantly lower in individuals with low HGS (p < 0.001). ROC analysis demonstrated that RHGS had excellent discriminatory ability with a corrected area under the curve (AUC) of 0.867. An optimal cutoff of 0.835 yielded a sensitivity of 66.7% and specificity of 96.4%. Lower RHGS was also associated with adverse metabolic parameters.
conclusionsRHGS demonstrated excellent discriminatory ability and may serve as a practical screening and confirmatory tool for identifying low muscle strength in prediabetic populations. RHGS, by accounting for body composition, may serve as an appropriate marker, especially in populations with heterogeneous BMI profiles. Integrating RHGS into routine prediabetes assessment can support early identification and prevention of sarcopenia.
