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/objective: The Simple Knee Value (SKV) is a knee-specific adaptation of the Single Assessment Numeric Evaluation (SANE), serving as a single-item patient-reported outcome measure for knee function. Although the SKV has been translated into Thai, its measurement properties have not yet been evaluated in patients with anterior cruciate ligament (ACL) injury. Therefore, this study aimed to evaluate the measurement properties of the Thai version of the SKV in this population. Methods: This prospective study included patients aged 18 to 50 years with ACL injury scheduled for surgery. Participants completed the Thai version of the SKV at three time points: preoperatively at baseline and 2 weeks later (for test-retest reliability), and 3 months postoperatively (for responsiveness). Three additional patient-reported outcome measures including the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF), the Knee Injury and Osteoarthritis Outcome Score (KOOS), and the European Quality of Life 5-Dimension 5-Level were administered at baseline and 3 months. Results: Ninety patients completed assessments at all time points. The Thai SKV demonstrated acceptable psychometric properties. Construct validity was supported by positive correlations with comparator patient-reported outcome measures (Spearman rank correlation coefficients = 0.20 - 0.37). Test-retest reliability was excellent (intraclass correlation coefficient = 0.92; 95% confidence interval 0.88 - 0.95). The SKV showed large responsiveness to change (effect size = 0.96, standardized response mean = 0.92) and good external responsiveness through moderate correlations with change scores of other instruments (Spearman rank correlation coefficients = 0.33 - 0.49). No floor or ceiling effects were observed. The minimal clinically important difference was 10.0 points (sensitivity 82.0%, specificity 100.0%). Conclusion: The Thai version of the SKV is a valid and reliable tool for evaluating knee function in patients with ACL injury. Responsiveness of the instrument was demonstrated in the early postoperative phase. This single-item measure offers a practical screening and monitoring tool for clinical practice where time-efficient assessment is required. For comprehensive patient evaluation, it should be used alongside detailed questionnaires such as IKDC-SKF or KOOS.
