Is Deceleration the Key Element in Vertical Jump Performance to Return to Sport After Anterior Cruciate Ligament Reconstruction With Hamstring Graft? A Preliminary Study.
Article in International journal of sports physical therapy, 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
Background/Purpose: Anterior cruciate ligament reconstruction (ACLR) often leads to persistent neuromuscular deficits, complicating return-to-sport decisions. Reliable functional assessments are needed to guide RTS after ACLR. The main objective was to examine countermovement jump (CMJ) measures to identify which parameters can best distinguish between ACLR and control participants. The secondary objective was to determine whether performance alterations between operated and non-operated limb exist during CMJ after ACLR. Design: Non-randomized, single blinded, cross-sectional study. Methods: Limb symmetry index (LSI) was calculated for vertical ground reaction force (vGRF), maximal power (MP), and eccentric rate of force development (RFDe) during countermovement jumps (CMJ) performed on force plates by an ACLR group (n=64) and a control group (n=47). First analysis compared LSI vGRF, LSI MP and LSI RFDe between groups. Secondary analysis compared vGRF, MP and RFDe between the operated/non-operated limb in the ACLR group and dominant/non-dominant limb in the control group. Between-group comparisons were made using Mann-Whitney tests due to non-normal data distribution. Effect sizes were calculated to assess the magnitude of differences. Results: Participants included 64 ACLR patients (mean age 26.5 ± 5.0 years; 33 females) and 47 controls (mean age 23.6 ± 2.1 years; 24 females). CMJ measures in the ACLR group were significantly reduced for LSI vGRF (p < 0.001), LSI MP (p < 0.001) and LSI RFDe (p < 0.001). The ACLR group exhibited significant differences between both limbs in terms of vGRF (p < 0.001), MP ( p < 0.001), and RFDe (p < 0.01). No significant limb differences were found in the control group. Conclusion: Measures of deceleration from the CMJ are altered after ACLR and should be considered throughout rehabilitation. Level of Evidence: 3.
