Psychometric Validation of the Persian Version of the Lysholm Score.
Article in Orthopaedic journal of sports medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: The Lysholm Knee Score (LKS) is a widely utilized patient-reported outcome measure for knee injury patients, due to its robust psychometric properties. It has been translated and validated in several languages, but it has not been translated into Persian. Purpose: To perform psychometric validation and cultural adaptation for the Persian version of the LKS (P-LKS) in patients with anterior cruciate ligament tears. Study Design: Cohort study (diagnosis); Level of evidence, 3. Method: The LKS was translated into Persian using a forward-backward translation procedure. To assess the reliability and validity of the P-LKS, responses were gathered from 100 consecutive patients (mean age, 35 ± 13 years; 91 male and 9 female). These participants also fulfilled the Persian versions of the International Knee Documentation Committee Subjective Form (IKDC-SF) and the 36-Item Short Form Health Survey (SF-36). Construct validity was evaluated by correlating the scores from the P-LKS with those from the Persian IKDC-SF and SF-36. Reliability was determined by examining test-retest reliability and internal consistency. Additionally, floor and ceiling effects, as well as measurement errors, were assessed. The Bland-Altman method was utilized to evaluate absolute agreement. Results: Construct validity was strong, as >80% of the predetermined hypotheses regarding correlations between the P-LKS and other measures were verified. The P-LKS exhibited a high correlation with the Persian IKDC-SF ( Conclusion: The study demonstrated that the P-LKS successfully preserved the attributes of the original version. It can be regarded as a reliable tool for Persian-speaking patients with complete anterior cruciate ligament tear.
