Beyond the Sagittal Plane: The Lateral Countermovement Jump as a Clinical Tool for Return-to-Play Decision-Making and Performance Evaluation.
Article in International journal of sports physical therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Return-to-play (RTP) decision-making after lower-extremity injury has traditionally emphasized sagittal-plane assessments, including double and single leg vertical jump metrics, double and single-leg hop batteries, and quadriceps strength limb symmetry indices (LSI). Yet many sports place a disproportionate demand on frontal-plane, lateral force production; basketball players, for example, spend up to a third of their live game actions in a defensive shuffle or lateral cutting posture. Recent force-plate evidence supports the single-leg lateral countermovement jump (LCMJ) as a reliable, time-efficient, and low-load assessment capable of stratifying lateral movement competency in elite athletes. This clinical commentary reviews recent reliability and discriminant-validity data on the LCMJ, places the test within the broader RTP evidence base and its known limitations, and proposes a practical framework for incorporating relative lateral force testing into RTP and performance batteries used by physical therapists and sports medicine clinicians.
