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
background and purposeThe massage gun is widely used to alleviate delayed-onset muscle soreness (DOMS); however, empirical evidence regarding its physiological effects remains limited.
objectivesThis study aimed to evaluate the acute effects of percussive massage on the quadriceps muscle's cross-sectional area (CSA), strength performance, and pain perception following a fatigue protocol.
methodsA randomized clinical trial was conducted including 37 physically active men. Participants performed a fatigue protocol on a 45° leg press, at 70% of their one-repetition maximum (1RM). The volunteers were allocated to an intervention group (G0 n = 19, mean ± SD; 25.7 ± 4.5 years, 83.7 ± 10.6 kg, 176.8 ± 6.3 cm) and control group (G1 n = 18, mean ± SD; 27.6 ± 5.0 years, 76.8 ± 15.7 kg, 174 ± 7.3 cm). Assessments were performed at baseline, 24 and 48 h, using ultrasound imaging, isometric dynamometer and VAS questionnaire (visual analog pain scale).
resultsRegarding the muscle area, significant increases were observed in the control group p < 0,05 for the rectus femoris at both measurement points compared with the baseline, which suggests that percussive massage may mitigate exercise-induced edema. While no statistically significant differences were observed between groups or across time points for muscle strength, G0 demonstrated a large effect size (d > 2.0) in strength maintenance at 24 and 48 h compared to G1. Both groups showed reduction in pain over time, while G0 demonstrated a significant decrease at 48 h compared to 24 h (53%, p < 0.001).
conclusionWithin-group assessments revealed significant reductions in pain perception over time for the intervention group. Regarding muscle strength, despite a large exploratory effect size observed during recovery, no statistically significant between-group superiority over passive rest was established. The findings suggest potential preliminary benefits for symptom relief without acute performance deficits.
