1 · What the graph read from 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.

2 · The registry

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

Introduction: The objective of this study was to investigate the perceived impact of the different phases of the menstrual cycle on football and futsal participation and identify barriers that may limit the performance and participation of Portuguese female players across competition levels. Methods: An online survey was conducted with the following inclusion criteria: registered participation in official football or futsal Portuguese leagues, an age of 18 years or older, and perceived regular menstrual cycles. A total of 197 answers were obtained and analyzed. Results: The majority of participants were 18-25 years old (61%), and 59% played futsal. Top-tier league players represented 15% of respondents, mid-tier 26%, and low-tier 59%. For the majority of respondents, the first 3 days of menstruation were perceived as having the most negative impact (66%), with abdominal pain, bloating, and breast tenderness being the most common symptoms. Players also associated the menstrual phase with decreased performance (endurance and power) and self-confidence, whereas they generally felt more confident and motivated during ovulation. No significant differences were found between sports (football and futsal) or competition levels in the perceived impact on performance and participation ( Discussion: These findings emphasize the need for better communication, education, and structural support to reduce menstruation-related barriers.
