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

The literature on nutrition in soccer has extensively focused on adult male and female soccer players, while knowledge regarding nutritional issues in youth soccer players remains limited. This review aims to summarize the findings related to nutritional habits and ergogenic aid practices among male youth soccer players. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) Checklist, four databases were consulted on September 17, 2024. Studies that included youth soccer players and examined daily energy intake or expenditure, as well as the effects of ergogenic aids on performance, met the eligibility criteria for this review. In total, 42 studies were considered. Among these, 22 studies focused on energy expenditure and dietary intake, while 20 studies investigated the effects of ergogenic aids on performance. Overall, a negative energy balance was observed; however, after adjusting for the underestimation of energy intake, an adequate intake compared to energy expenditure was found in this review. Additionally, carbohydrate intake tended to decrease with age, while protein intake remained stable throughout adolescence. The topic of macronutrient periodization in youth players requires further research, as no data is currently available regarding macronutrient intake. Additionally, data concerning the effects of ergogenic aids on performance is limited due to variability in methodological procedures. Nevertheless, caffeine and creatine appear to have a positive effect on physical capabilities. This review provides reference data for nutritionists working with youth soccer players and highlights the need for future research in this area.
