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
backgroundAnthropometric characterization and somatotype profiling in professional soccer players are essential for understanding the morphofunctional demands associated with playing positions.
objectiveTo determine and compare anthropometric profile and somatotype characteristics across playing positions in professional female soccer players, and to analyze their relationship with nutritional adequacy.
methodsA cross-sectional study was conducted with 43 players from two First Division teams in Trujillo (Peru). Anthropometric measurements followed ISAK standards, and body composition was estimated using Kerr's five-component fractionation method. Somatotype was assessed using the Heath-Carter method. Nutritional adequacy was calculated according to playing position and international recommendations. Statistical analysis included the Kruskal-Wallis test, Chi-square tests, and Kendall's Tau correlations. Due to sample size, goalkeeper data (n = 4) were treated purely as a descriptive case series for correlational analyses.
resultsGoalkeepers presented significantly higher adipose mass (18.6 ± 2.5 kg) and muscle mass (33.1 ± 2.2 kg) than outfield players (p < 0.05; ε² ≥0.21). Nutritional adequacy differed significantly by position, with goalkeepers displaying a descriptive 100% prevalence of protein insufficiency. For outfield players, no significant associations were found between nutritional adequacy and body composition when stratified by position (p > 0.05). However, in the total sample, protein adequacy was inversely correlated with adipose mass (Tb = - 0.60, p < 0.001), and lipid adequacy was negatively associated with muscle mass (Tb = - 0.52, p < 0.001).
conclusionsAlthough no position-specific associations were identified among outfielders, significant relationships emerged in the overall sample, suggesting that nutritional adequacy is significantly associated with body composition, appearing to be a relevant factor independently of tactical role.
