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: Manipulating relative pitch size is a common practice in soccer training; however, published evidence on its true effects for practical coaching purposes has been lacking in the scientific literature. This review aimed to identify and quantify changes in physiological, physical, technical, and tactical variables resulting from increases in relative pitch size during small-sided games (SSGs) in soccer. Methods: A literature search was conducted, resulting in the inclusion of 56 articles in this review. Linear regression analysis was performed to examine the total and percentage changes in relative pitch size and its influence on physiological, physical, technical, and tactical variables collected during SSGs. Results: Linear regression revealed that an increase in relative pitch size was significantly positively associated with higher values in lactate, RPE, and Edwards' TRIMP ( Conclusion: Larger relative pitch sizes can be implemented as a task constraint in SSGs to enhance physiological (e.g., lactate, RPE), physical (e.g., total distance, number of sprints), and tactical variables (e.g., surface area). Caution should be exercised regarding the potential negative impact on technical outcomes when increasing relative pitch size. Practitioners in soccer can utilize the findings of this review to achieve desired effects by adjusting relative pitch size to target specific training outcomes.
