The Effect of Photobiomodulation Therapy on Muscle Performance in Volleyball and Football Players: A Meta-Analysis of Randomized Controlled Trials.

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
contextThe use of photobiomodulation therapy (PBMT) as an adjunct to improve muscle performance and accelerate recovery in high-level volleyball and football players remains controversial.
objectiveTo determine whether PBMT improves skeletal muscle performance in ball sports athletes, and whether there are differences in the improvement of skeletal muscle performance by PBMT between volleyballers and footballers. DATA SOURCES: A comprehensive search of the Web of Science, Medline, Scopus, and PubMed databases was conducted through April 10, 2025. STUDY SELECTION: Eligible studies included those explicitly categorized as randomized controlled trials (RCT) of PBMT interventions for high-level volleyballers and/or footballers; 14 studies met the inclusion criteria. STUDY
designMeta-analysis. LEVEL OF EVIDENCE: Level 2. DATA EXTRACTION: The primary outcome measures included maximal voluntary contraction force (MVC), number of repetitions, and creatine kinase (CK) levels. Means and standard deviations for each variable of interest were used to calculate standardized mean differences (SMDs).
resultsThe active laser had no significant effect on MVC (mean difference [MD], 19.67; 95% CI, 7.36 to 31.72;
conclusionPBMT can delay muscle fatigue onset and reduce CK levels in ball sports athletes. The improvement in skeletal muscle performance induced by PBMT showed differences between volleyballers and footballers, as there was a significant increase the number of repetitions in volleyball players, whereas a significant decrease in CK levels was noted in footballers.
