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.

Abstract
backgroundAnterior cruciate ligament (ACL) injuries are common knee injuries that impair postural stability due to the loss of mechanoreceptors, affecting proprioceptive feedback and sensorimotor control. The aim of our study was to comprehensively investigate the postural stability in non-athletic individuals who had undergone ACL reconstruction (ACLR) and exploring their relationship with patient-reported outcomes.
methodsA total of 58 participants were included in the study, consisting of 29 individuals who underwent ACLR and 29 control group participants matched for age, height, weight, and sex. Static stability (bipodal and single-leg) was assessed using a force plate by evaluating center of pressure (COP) parameters, while dynamic stability was measured with the Y-Balance Test. During tests, the operated limb in the ACL group was compared with the non-dominant lower extremity of the control group. Group comparisons were performed using independent sample t-tests and Mann–Whitney U tests, and within-group analyses were conducted using paired sample t-tests or Wilcoxon tests. Spearman correlation analysis was used, and statistical significance was set at p < 0.05.
resultsWhen comparing bipodal stance scores between the groups, the ACL group exhibited greater anteroposterior amplitude of the COP sway (p < 0.001). No differences were observed between the operated and non-operated limbs in single-leg stance parameters (p > 0.05); however, when compared with the control group’s non-dominant limb, the control values were better than the operated limb (p < 0.05). In the Y-Balance Test, anterior reach and composite scores were significantly lower on the operated limb (p < 0.05). When compared with the control group, the ACL group demonstrated lower performance in anterior, posterolateral and posteromedial reaches, as well as composite scores (p < 0.05). No clinically relevant limb-symmetry deficits were observed within the ACL group (p > 0.05).
conclusionIn non-athletic individuals, limb symmetry was achieved in static postural stability tests post-operatively; however, differences compared to healthy individuals persisted. Postural deficits were more pronounced particularly in single-leg stance and dynamic postural stability tasks. These findings suggest that postural stability deficits in non-athletic populations may persist at least 12 months post-surgery.
