Effect of an Arm-Span-Adjusted Hand Position on Closed Kinetic Chain Upper Extremity Stability Test Performance and Muscle-Related Body Composition Associations.

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
backgroundThe Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) is used to assess upper-extremity performance in a closed kinetic chain position. The standard hand placement of 36 inches may favor individuals with larger body dimensions.
methodsSixty-five healthy adults (44 males, 21 females; 18-33 years) performed the CKCUEST under two conditions: the standard position and a modified position with hand distance set at 50% of arm span. The mean number of touches, standard score, and power score were calculated for each condition. Reliability and the effects of sex and body composition were also examined.
resultsPerformance was significantly better in the modified position for mean touches (24.4 ± 4.47 vs. 23.0 ± 4.62,
conclusionsAn arm-span-adjusted hand position improves CKCUEST performance and may provide a fairer assessment across individuals with different body dimensions.
