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: Patient-reported outcomes (PROs) are considered the gold standard for evaluating value-based care in orthopaedics. However, there is little evidence to guide implementation of PROs for surgeon performance evaluation. Purpose: To develop a risk-adjusted surgeon performance measure using the Knee injury and Osteoarthritis Outcome Score (KOOS) for patients undergoing anterior cruciate ligament reconstruction (ACLR). Study Design: Cross-sectional study; Level of evidence, 3. Methods: Patients (N = 1248; 662 men; mean age, 30 ± 13 years) who underwent ACLR performed by 40 surgeons between 2010 and 2018 were identified from a large, nationally representative sports medicine clinical data registry. Linear regression was used to predict change scores for each KOOS subscale (Pain, Symptoms, Activities of Daily Living [ADL], Function in Sports and Recreation, and Knee-Related Quality of Life) while adjusting for patient baseline characteristics. A risk-adjusted performance measure was calculated for each KOOS subscale as the difference between the unadjusted and the risk-adjusted predicted change score across all patients treated by a single surgeon. Surgeon-relative quartile ranking was compared across outcome subscale scores. Results: One-third of the patients (34%) displayed acute cartilage damage, and 56% had a meniscal injury. In the risk adjustment models, older age, presence of diabetes, current smoking status, acute cartilage damage, concurrent cartilage treatment, lower baseline Veterans RAND 12-Item Health Survey mental and physical component scores, and lower baseline Marx and KOOS subscale values all had a significant negative influence on the predicted KOOS subscale change values ( Conclusion: These results showed that surgeon performance varies widely when evaluated using different KOOS subscales for patients undergoing ACLR. Based on the preliminary results and clinical perspective, the authors recommend the ADL and Symptoms subscales as the best options to differentiate surgeon performance for these patients. However, evaluation of surgeon performance may require consideration or use of a set of PROs or the development of a single index PRO that is sensitive to the range of outcome dimensions important to patients.
