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
Purpose: To evaluate whether patients requiring surgical reintervention for postoperative stiffness following multiligament knee reconstruction achieve comparable functional outcomes to those who do not require additional surgery. Methods: A retrospective cohort study was conducted including patients who underwent surgical reconstruction for multiligament knee injuries between January 2015 and February 2023 at a single level-1 trauma centre, with a minimum follow-up of 24 months. Patients who developed postoperative flexion stiffness requiring arthroscopic fibroarthrolysis combined with manipulation under anaesthesia were identified and compared with those who did not require reintervention. The primary outcomes were the Lysholm score and Knee injury and Osteoarthritis Outcome Score (KOOS4) score at final follow-up. Results: A total of 95 patients were included in the final analysis, of whom 16 (16.8%) required surgical reintervention for postoperative stiffness. The mean age was 38.4 ± 13.5 years and the mean follow-up was 73.2 ± 25.1 months. The median time from index surgery to fibroarthrolysis was 5.0 months (interquartile range, 4.0-8.3). At final follow-up, no statistically significant differences were observed between groups in KOOS4 score (57.9 ± 2.8 vs. 62.9 ± 5.4; Conclusion: Patients who required surgical reintervention for postoperative stiffness after multiligament knee reconstruction achieved functional outcomes comparable to those who did not require additional surgery. Arthroscopic fibroarthrolysis combined with manipulation under anaesthesia appears to be a safe and effective treatment option in this setting, supporting its consideration when conservative management has been exhausted. Level of Evidence: Level III, retrospective cohort study.
