Vertical jump performance in recreational runners with visual impairment: a cross-sectional study.
Article in PeerJ, 2025. 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
Background: Runners with visual impairment (VI) may show changes in jump technique due to momentary loss of spatial reference specifically related to the base of support on the ground and rapid postural adjustment. The vertical jump performance and the analysis of the technique can provide information about the neuromuscular characteristics of the runners with VI, motor control and training strategies. Objective: Thus, the purpose of this study was to analyze the relationship between vertical jump performance and lower limb joint angles in recreational runners with VI. Methods: Eight recreational runners (age 33.9 ± 12.7 years and body mass 64.1 ± 13.6 kg) with VI (visual classification: 4 T1, 2 T2 and 2 T3) performed five consecutive squat jumps (SJ) and five consecutive countermovement jumps (CMJ) with 5 min of rest between them. The vertical jumps were recorded by one camera and the jump height and power were evaluated using accelerometer Myotest. Results: No difference was found between the SJ (16.8 ± 4.9 cm) and CMJ performances (13.6 ± 5.8 cm) ( Conclusion: We concluded that recreational runners with VI reach higher jump heights in a deeper squat position during SJ.
