Effects of two warm-up protocols on isokinetic knee strength, jumping ability and sprint swimming performance in competitive swimmers.
Trial report in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
The purpose of this study was to examine the effects of different dryland warm-up protocols on knee isokinetic strength, vertical jumping, and sprint performance in competitive swimmers. Twenty-four male swimmers were randomly assigned to the FIFA 11 + group (n = 12) or the post-activation performance enhancement (PAPE) group (n = 12). The FIFA 11 + group performed the FIFA 11 + warm-up program three times per week for 6 weeks, whereas the PAPE group consisted of performing general activities and three sets of five drop jumps. Performance test included concentric (con) and eccentric (ecc) isokinetic strength of the quadriceps (Q) and hamstrings (H) of the dominant (DL) and non-dominant (NDL) limbs at three angular velocities, countermovement jump (CMJ), squat jump (SJ) and a 50-m time trial. The conventional (Hcon: Qcon) and functional (Hecc: Qcon) ratios were calculated pre- and post- intervention. The FIFA 11 + group showed a significant increase in DL-Hcon (p < 0.05, ES = 1.0-1.8), and NDL-Hcon (p < 0.05, ES = 1.0-1.6) in all angular velocities, and DL-Qcon (p < 0.05, ES = 0.9) at 60°·s
