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

Objective: To compare lower-extremity neuromuscular and biomechanical characteristics during single-leg drop landing under single-task and cognitive-motor dual-task conditions in individuals with chronic ankle instability (CAI). Methods: Twenty-three male participants with unilateral CAI completed single-leg drop landings from a 30-cm platform under single-task and auditory 2-back dual-task conditions in randomized order using a within-participant repeated-measures design. Whole-body three-dimensional kinematics, ground reaction force (GRF), and surface electromyographic (sEMG) signals from eight muscles of the affected limb were recorded synchronously. Outcomes included GRF and dynamic-stability measures, hip, knee, and ankle joint angles and internal moments, muscle activation, and co-contraction indices (CCIs). Depending on the distribution of paired differences, two-sided paired-samples Results: Compared with the single-task condition, the dual-task condition produced a higher peak vertical GRF (vGRF; Conclusion: In individuals with CAI, a concurrent working-memory task was associated with higher peak impact, reduced hip flexion at selected post-contact events, and selective changes in net internal joint moments and lower-extremity sEMG measures. These findings indicate that dual-task effects on landing control are outcome- and event-specific rather than uniform across biomechanical and neuromuscular domains.
