Evaluation of eccentric and concentric force during vertical jump after anterior cruciate ligament reconstruction: a comparative study.
Article in BMC sports science, medicine & rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07448064 (Analysis of Biomechanical Alterations During the Eccentric Phase of the Countermovement Jump in Patients After Anterior Cruciate Ligament Reconstruction), which is not on this map.

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.

Abstract
backgroundAnterior cruciate ligament reconstruction (ACL-R) significantly affects lower limb biomechanics, particularly during dynamic movements like jumping. The countermovement jump (CMJ) is a commonly used test to evaluate force production and asymmetry in post-ACL-R individuals. This study aimed to compare eccentric and concentric forces during the CMJ between ACL-R patients and healthy controls.
methodsThis retrospective study included 56 ACL-R patients and 47 recreational athletes. All participants performed CMJs on a dual force plate to measure eccentric mean force (ECC), Concentric mean force (CON), and limb symmetry index (LSI). A mixed ANOVA was performed to compare ECC LSI and CON LSI between the ACL-R and control groups.
resultsCMJ height was significantly lower in the ACL-R group compared to the control group (-25.4%, p < 0.001), with a lower ECC LSI (-7.7%, p < 0.001) and CON LSI (-10.0%, p < 0.001).
conclusionSix months after ACL-R, both eccentric and concentric force production remain compromised, with significant inter-limb asymmetries. These findings highlight the need for targeted rehabilitation strategies to restore force symmetry and optimize return-to-sport readiness.
