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

Purpose: This case study presents a 25-week nutritional period and body mass management strategy for a Mexican world champion that competes in the super bantamweight category. While the primary goal was to achieve competition weight, the intervention revealed unexpected physiological adaptations to prolonged energy restriction. Methods: A structured nutritional plan was implemented using multiple indicators of nutritional status. Assessments included anthropometry, hemoglobin concentration, creatine kinase activity, and urine specific gravity. The resting metabolic rate (RMR) and respiratory exchange ratio (RER) were measured six times. Dietary intake was recorded via the ASA24® Dietary Assessment Tool. Strength was evaluated via isometric dynamometry (legs, chest, and back) and grip strength. VO Results: After 23 weeks, the athlete's body mass decreased by 23.7 kg (30.1%), and the sum of the six skinfolds decreased from 106 mm to 67 mm. The RER decreased from 0.92 to 0.78, indicating improved metabolic flexibility. VO Conclusion: These findings illustrate potential individual variability in physiological responses during prolonged energy restriction in weight-class sports. The coexistence of elevated RMR, changes in body composition, and improved physical function highlights the complexity of athlete adaptation and underscores the need for further research in elite combat sport athletes.
