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

This randomized parallel-group study examined the effects of curvilinear sprint (CS) training with different radii on linear sprint (LS) performance, CS ability, change of direction (COD), and horizontal force-velocity (FV) profile in youth soccer players. Eighteen male youth soccer players from the same academy were randomly assigned to a narrow CS group (NCSG; 5.15 m radius) or a wide CS group (WSCG; 11.15 m radius). Both groups completed 12 CS sessions over 6 weeks (2 sessions/week), integrated into their regular team training. Pre- and post-intervention assessments included LS (5-30 m), CS tests on both the good and weak sides over two radii (7.15 m and 9.15 m), modified 505 COD test, and sprint mechanical variables from the FV profile (F
