Reliability and Correlations Among Handgrip Strength Measurements and Muscle Power in Older Women.

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
objectivesThe reliability of handgrip strength measurements and their relationship with muscle power in older adults is not well understood. This study aimed to determine the reliability and correlations between handgrip strength measurements and muscle power in older women.
methodsTwenty older healthy women (67.8±5.8 years) participated in two separate testing sessions. During each session, handgrip contractions were performed to evaluate strength, specifically measuring peak force and rate of force development (RFD) across various time intervals. Muscle power was assessed by measuring sit-to-stand peak power and seated medicine ball throw distance.
resultsHandgrip strength measurements, sit-to-stand peak power, and seated medicine ball throw distance demonstrated good test-retest reliability. The intraclass correlation coefficients were between 0.930 and 0.978. The coefficients of variation were between 2.7 and 8.0%. There were significant correlations between handgrip strength measurements and both sit-to-stand peak power (r = 0.485-0.533, P = 0.015-0.030) and seated medicine ball throw distance (r = 0.457-0.634, P = 0.003-0.043).
conclusionsOur study showed good reliability for handgrip strength measurements, sit-to-stand peak power, and seated medicine ball throw distance in older women. The significant correlations we observed suggest that handgrip peak force and RFD may be important variables associated with one's muscle power.
