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

Background: Chronic low back pain (CLBP) is common among adolescent athletes, particularly baseball players; however, its association with body composition remains unclear. Purpose: To investigate the relationship between body composition parameters and the presence of CLBP in high-school baseball players. Study Design: Retrospective cohort study. Methods: Male high-school baseball players were recruited and divided into the CLBP and non-CLBP groups. CLBP was defined as low back pain rated ≥3 on the numerical rating scale (NRS) and lasting >12 weeks. Body composition was measured using bioelectrical impedance analysis in the first year of high school. Logistic regression was used to identify the factors associated with CLBP. Results: Ninety male baseball players participated (mean age: 16.8±0.4 years, during second year). The CLBP group (n=31) showed significantly higher percentage body fat (PBF), body fat mass (BFM), BFM index, and trunk fat mass compared with the non-LBP group (n=59). Logistic regression analysis identified first-year NRS scores (odds ratio [OR]: 2.10; 95% confidence interval [CI]: 1.46-3.21) and PBF (OR: 1.26; 95% CI: 1.05-1.51) as significant predictors of CLBP. Conclusion: Elevated body fat percentage and elevated pain intensity in early high-school years were associated with the development of CLBP among high-school baseball players. Regular monitoring of body composition and early intervention based on pain levels may effectively prevent CLBP in adolescent baseball players, thereby supporting better long-term athletic performance and health outcomes. Level of Evidence: 3b.
