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

Many contact sport athletes have high body mass index (BMI) and high metabolic disease risk. Rapid weight gain in first-year athletes may further increase this risk and affect gastrointestinal status. This study examined metabolic risk factor and gut microbiota during weight gain in 21 first-year male college athletes. We included members of student clubs for American football and rugby (ATH) and 10 controls without regular exercise habits (CON). Baseline measurements were taken within 3 months of joining the club, with follow-up after 6 months. B-mode ultrasound and blood and stool samples were analyzed. At the 6-month follow-up, the ATH group showed significant increases in body weight, weight-adjusted thicknesses of subcutaneous fat and abdominal cavity, and triglyceride levels, while gut microbiota diversity significantly decreased. No significant differences were observed in the CON group. The rate of change in body weight in the ATH group was significantly positively correlated with the change in triglyceride levels (r
