1 · What the graph read from it

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.

2 · The registry

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

purposeThe present study aims to provide normative values for Hand Grip Strength (HGS) and Hand Pinch Strength of healthcare staff and evaluate key body anthropometric predictors of these strengths.

methodsThis cross sectional study was conducted on 2,337 healthcare staff. HGS and pinch strength were assessed for both hands using a hydraulic hand dynamometer and pinch gauge. Descriptive data were reported for dominant and non-dominant HGS and pinch strength, after stratification by gender, age, and height. Multivariatelinear regression analysis was performed to assess predictor variables.

resultsThe maximum HGS values were identified in men aged 35 to 40, measuring 38.00 ± 7.81 kg, and in women aged 50 to 55, measuring 22.20 ± 4.13 kg. The highest pinch strength values were recorded in men aged 45 to 50, with measurements of 7.16 ± 1.48 kg, and in women aged 35 to 40, with measurements of 4.24 ± 1.15 kg. The predictor variables for dominant HGS and pinch strength exhibited 59% and 51% prediction for variations in dominant HGS and pinch strength, respectively, using gender, height, and wrist circumference as predictors. Height (for grip: dominant hand: β = 0.33, CI [0.28, 0.37]; for pinch: dominant hand: β = 0.04, CI [0.02, 0.05]) was the most effectively correlated anthropometric variable.

conclusionThe findings demonstrate differences in HGS and pinch strength among different gender and age groups. Multiple linear regression analysis highlights the crucial role of anthropometric variables in evaluating hand strength. These results can provide guidance for future research and clinical assessments. TRIAL REGISTRY NUMBER: Not applicable. LEVEL OF EVIDENCE: Level III (analytical cross-sectional study on big sample size).
