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
Upper-body muscular power and repeated sprint ability are recognized as important contributors to sprint swimming performance. However, the relative and combined predictive value of dry-land power measures and in-water repeated sprint ability for 50-m freestyle performance remains insufficiently understood. This study aimed to examine the relationships between upper-body muscular power, repeated sprint swimming variables (RSS), and 50-m freestyle performance in competitive swimmers. Thirty-six national-level male swimmers (age: 16.4 ± 0.3 years) participated in this cross-sectional study. Each swimmer completed: (1) an upper-body load-velocity assessment using the bench press on a Smith machine equipped with a linear position transducer to determine peak power; (2) an in-water repeated sprint test (8 × 15 m, 30 s rest) to determine fastest time, mean time, fatigue index, and total time; and (3) a maximal 50-m freestyle time trial. Pearson correlations revealed a very strong negative relationship between maximum muscular power and 50-m time (r = -0.86,
