Handgrip Strength and Muscle Mass Indices in the Assessment of Muscle Strength and Muscle Mass Parameters in Women Aged 65-75 Years with Low Physical Activity.
Observational study in Nutrients, 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
backgroundAge-related alterations in body composition, including the decline of skeletal muscle mass and strength, combined with increased adiposity, contribute to sarcopenia risk in older adults. Handgrip strength (HGS) is widely used as a functional marker of muscle health.
objectiveTo evaluate the associations between body composition, handgrip strength, and step-based physical activity in women aged 65-75 years. MATERIAL AND
methodsA cross-sectional observational study was conducted in 246 community-dwelling women. Body composition, including Skeletal Muscle Index (SMI), was assessed using bioelectrical impedance analysis. Handgrip strength was measured with dynamometry according to the Southampton protocol. Physical activity was evaluated using pedometers. Group comparisons and correlation analyses were performed.
resultsOverweight or obesity was present in 75% of the participants. Reduced SMI was observed in 62.1% of women, while low HGS (<20 kg) occurred in 78.0%. Women with normal SMI demonstrated significantly higher HGS values. HGS correlated positively with lean body mass and SMI but not with BMI. Participants achieving ≥ 5000 steps/day showed significantly higher muscle mass indices and strength.
conclusionUnfavorable body composition and reduced muscle strength were highly prevalent. HGS was strongly associated with muscle mass parameters, supporting its role as a functional marker independent of BMI. Step-based activity was associated with more favorable muscle-related outcomes.
