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: Postoperative knee arthrofibrosis after arthroscopic ligament reconstruction is a serious complication. Among adolescents, risk factors for postoperative arthrofibrosis are not well characterized and the effectiveness of early manipulation under anesthesia (MUA) is not well established. Purposes: To identify risk factors for arthrofibrosis after arthroscopic knee ligament reconstruction in adolescent patients and to evaluate the safety and effectiveness of early MUA. Study Design: Case-control study; Level of evidence, 3. Methods: The charts of all adolescent patients (<19 years of age) who underwent early MUA (<3 months) for knee stiffness after anterior cruciate ligament (ACL) or medial patellofemoral ligament (MPFL) reconstructions between 2008 and 2021 were retrospectively reviewed. Patients were matched 2:1 with patients without MUA from the same study period. The primary outcome was the final range of motion (ROM) after MUA. Logistic regression analysis was performed to identify predictors of MUA. Results: A total of 25 patients (10 with ACL reconstruction and 15 with MPFL reconstruction) with a mean age of 14.8 ± 2.6 years were included for analysis. Overall, 44% were skeletally immature. Patients underwent MUA at a mean of 63.3 ± 19.5 days after the index surgery. The mean ROM improved significantly from 96.3°± 20.5° to 135°± 9.7° after MUA after a median follow-up of 8.1 months (interquartile range, 5.4-15.0 months). There were no complications associated with MUA, but 2 patients (8.0%) had MUA treatment failure. There were no differences in body mass index, type and frequency of associated procedures, or patellar height on lateral radiographs between the cohorts. The MUA cohort had statistically significant increased operative time, decreased preoperative motion, decreased ROM at 6 weeks postoperatively, and increased pain at 6 weeks postoperatively when compared with the non-MUA cohort. Regression analysis demonstrated that ROM at 6 weeks (OR: 0.83, 95% CI, 0.69-0.98, Conclusion: The findings of this study suggest that early (<3 months) MUA is safe and effective in treating knee arthrofibrosis in adolescent patients. MUA is a treatment alternative for patients with restricted ROM at 6 weeks that may help them recover full ROM.
