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

Biomechanical theory and coaching heuristics suggest that contact depth meaningfully constrains swing mechanics and batted-ball outcomes. Our purpose was to examine the relationship between contact depth and key hitting metrics during live collegiate competition. Markerless motion capture and ball tracking data were collected during live NCAA Division I games from 2779 batted balls from 239 hitters. Outcomes included contact depth, exit velocity, maximum swing speed, swing speed at contact, and vertical and horizontal attack angles. Regressions assessed relationships with velocity and swing speed variables, while partial least squares regression evaluated attack angles. The mean contact depth was 20.1 ± 7.2 inches in front of the hitter's center of mass. Contact depth weakly explained exit velocity (r
