Taping for jump performance: The effects of various knee taping techniques on a drop jump.
Article in South African journal of sports medicine, 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: Drop jump landing (DJL) analysis is used to identify an athlete's reactive strength abilities and landing mechanics. The aim of the study was to investigate the effects of different knee taping conditions on lower limb kinetics and kinematics during a DJL. Objectives: The aim of the study was to investigate the effects of different knee taping conditions on lower limb kinetics and kinematics during a DJL. Methods: Twenty-one athletes (age: 22.0±2.7 years; height: 1.68±0.08 m; mass: 63.3±10.6 kg) performed a series of 40cm drop jumps under four taping conditions - no tape (NT), dynamic tape (DT), rigid tape (RT), and kinesio-tape (KT). Reactive strength indices (ground contact time (GCT), Landing impact force, and reactive strength index (RSI)) were compared across conditions to determine reactive strength performance. Continuous biomechanical data were analysed using SPM1d repeated measures ANOVA (p<0.05). Results: Significant changes were observed in ground reaction force (GRF) (3-7%, p=0.001) between NT vs RT and KT, GCT (p=0.003) between NT vs KT, RSI (p=0.013) between NT vs KT, peak ankle abduction (p=0.05) and peak knee rotation (p<0.001). SPM1d analyses revealed significant changes in ankle rotation (1-6%; 17-20%; 67-100%), knee abduction (14-16%; 49-51%) and rotation (1-15%; 17-40%; 51-100%), and hip rotation (16%; 71-100%). Conclusion: The knee taping conditions showed minor kinematic changes to the ankle, knee, and hip joint angles. Further, the kinetics revealed that KT showed the most improvement in reactive strength performance, having the highest GRF, contributing to SCC efficiency, and the shortest GCT, yielding the highest RSI. This suggests that KT on the knee may contribute to reactive strength performance in a DJL.
