Impact of The Menstrual Cycle on Physical Recovery after Small-Sided Games: A Crossover Study in Women's Soccer Players.
Trial report in Journal of sports science & medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 aim of this study was twofold: (i) to compare potential variations in reactive strength index (RSI), interleukin-6 (IL-6), and delayed onset muscle soreness (DOMS) between the early follicular and mid-luteal phases in response to small-sided games (SSGs); and (ii) to analyze potential interactions in the magnitude of responses to different SSG formats, specifically 1v1 and 5v5. A crossover study design was employed, involving 20 amateur female soccer players (age: 21.4 ± 1.8 years) who were randomly assigned to two groups. With a 15-day interval between sessions, participants underwent repeated assessments following 1v1 and 5v5 formats across two menstrual cycle phases (based on calendar estimates). Participants completed 1v1 and 5v5 sessions and were evaluated at four time points: at rest, immediately post-session, 24 hours post, and 48 hours post. A three-way repeated measures ANOVA was used to assess the effects of play format (1v1, 5v5), hormonal phase (early follicular, mid-luteal), and time (rest, post-exercise, 24h, 48h). RSI was assessed using a drop jump test, IL-6 was measured via salivary analysis, and DOMS was rated using a Likert scale. To control for potential confounders like nutrition, sleep, and training load, participants maintained their regular diet and training during the study, though individual variation in these factors could still affect the results. Significant interactions were found between menstrual cycle phase, format, and time for RSI (p = 0.040; ηp
