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

introductionDiscrepancies exist in findings on how varying body mass index (BMI) levels impact physical training-related injuries across different studies. This systematic review and meta-analysis aimed to evaluate the relationship between BMI and physical training-related injuries both qualitatively and quantitatively.

methodsA comprehensive search of the MEDLINE, Cochrane and EMBASE databases was performed. The study selection followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic review and meta-analysis were conducted using weighted data and a random-effects model. Subgroup analyses were based on gender and military service branches. Heterogeneity among the studies was assessed through the I

results33 studies were included in the analysis, with abnormal BMI (underweight, overweight and obesity) identified as a clear risk factor for training-related injuries (overall RR=1.21, 95% CI 1.15 to 1.27; male RR=1.16, 95% CI 1.08 to 1.23; female RR=1.05, 95% CI 1.02 to 1.09). No significant heterogeneity was observed among navy, army and air force personnel (p=0.58), although abnormal BMI remained a notable risk factor in both the army and air force. Meta-regression analysis indicated that the lowest injury risk occurred at a BMI of 23 kg/m

conclusionFindings suggest that abnormal BMI increases the risk of training injuries among military personnel and that this risk varies with age and the duration of training. Emphasis should be placed on risk prevention in the early stages of military training and on enhanced protection for high-risk populations.
