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.

Abstract
backgroundThis study aimed to examine the effects of stretching, strength, and plyometric exercise programs, implemented in addition to regular training, on jumping performance and knee valgus angles in football players.
methodsParticipants were randomly assigned to an experimental or a control group. The experimental group engaged in an eight-week program that included stretching, strength, and plyometric exercises, while the control group continued their standard training regimen. Jumping performance variables, including Countermovement Jump (CMJ), Free CMJ, Drop Jump (DJ), Squat Jump (SJ), Horizontal Jump, and right and left knee valgus angles, were assessed at three different time points. Demographic characteristics were measured using a scale and meter, and the “My Jump 2” application was used for jump tests and knee valgus evaluations. Data were analyzed using SPSS 27. Repeated Measures ANOVA with Bonferroni post hoc comparisons was employed to analyze within-group changes, while Independent Samples T-tests were used to assess between-group differences.
resultsBoth groups demonstrated increased jumping performance following the intervention; however, the experimental group showed significantly greater increases across all jump parameters. Furthermore, while reductions in right and left knee valgus angles were observed in both groups, these reductions were more pronounced in the experimental group.
conclusionThe findings indicate that supplementing regular training with stretching, strength, and plyometric exercises significantly enhances jumping performance and more effectively reduces knee valgus angles in football players. These results suggest that such complementary training programs can play a critical role in improving athletic performance and reducing injury risk.
