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

Introduction: Academic achievement is typically treated as a single outcome, obscuring the differing demands of theoretical and practical coursework. We examined how health, sleep quality, fitness, energy drink consumption, and sport status relate to performance across course types. Methods: Questionnaire data from 530 first-year kinesiology students (University of Zagreb, 2022/23-2024/25) were linked to official records of final grades in 11 courses. Ordinary least squares models with robust standard errors were estimated for overall GPA and six course-specific GPAs. Results: Males scored 0.21 points lower than females, most markedly in theoretical courses. Better self-rated health and fitness predicted higher grades. Sleep quality was unrelated to overall GPA but positively associated with team-sport grades. Energy drink intake showed a U-shaped association; professional athletes underperformed in theoretical courses. Discussion: Predictors of academic success operate differently across course types, supporting targeted academic support and health-promotion initiatives; the cross-sectional design precludes causal inference.
