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
backgroundIt is recommended to prescribe sets to volitional muscular failure (e.g., 4 sets) or a fixed repetition scheme of 75 repetitions (1 × 30, 3 × 15) in low-load resistance exercise with blood flow restriction (BFR-RE). While prior studies suggest both protocols may elicit similar muscular adaptations, the extent to which this is explained by matched exercise volume remains unclear.
objectivesThis systematic review and meta-analysis evaluated the number of repetitions performed during four sets of low-load BFR-RE to volitional muscular failure and compared these with the fixed 75-repetition scheme. The goal was to determine whether the two protocols yield similar total and per-set repetition volumes.

resultsAcross 25 studies (47 means; n = 678), the estimated total repetitions performed to failure was 73.1 (95% CI: 61.1 to 85.2). Per-set means were 36.0 (95% CI: 30.5 to 41.4), 14.7 (95% CI: 12.2 to 17.1), 11.5 (95% CI: 9.2 to 13.8), and 10.4 repetitions (95% CI: 8.1 to 12.7) for sets 1 through 4, respectively.
conclusionFour sets of BFR-RE to volitional muscular failure produce similar total repetition volume compared to the commonly implemented fixed 75-repetition scheme, though the distribution of repetitions per set differs. These findings provide insight into the mechanical equivalence of two widely used BFR-RE prescriptions.
