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
Introduction: Assessing unilateral jumping performance and its determinants is important in handball, as it underpins key offensive and defensive actions. This study aimed to evaluate the intra-session reliability of a modified single-leg horizontal jump (SLHJ) test in elite players and its associations with hip and trunk strength. Methods: Eighty elite handball players performed three single-leg horizontal jumps (SLHJs) using both their preferred and non-preferred push-off legs. Jump distance, side deviation, and resultant jump angle were measured as dependent variables. Unilateral maximal and explosive isometric strength of the hip abductors, adductors, extensors, flexors, and lateral trunk muscles were assessed as independent variables. Results: SLHJ reliability was poor-to-moderate for side deviation and jump angle (ICC Discussion: Due to lower reliability, directional SLHJ measures should be interpreted with caution. Hip strength was partially supported as a determinant of SLHJ performance in elite handball players. The modified SLHJ better reflects performance differences related to hip strength in the non-preferred leg.
