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
purposeTo introduce the 'three-in-one' surgical procedure, and to report its clinical outcomes.
methodsThis retrospective clinical study included 42 skeletally immature patients with habitual patellar dislocation who underwent a 'three-in-one' surgical procedure from 2017 to 2022. This procedure comprised an extensive lateral release, half medial transfer of patellar tendon with subperiosteal fixation, and reconstruction of the medial patellofemoral ligament with semitendinosus autograft. The clinical results were evaluated using preoperative and postoperative functional score and imaging.
resultsAll patients returned for follow-up at a mean of 52.1 ± 9.2 months after surgery. There was no recurrence of dislocation or severe complications. All the patients have resumed full activities with satisfactory knee function. There was a statistically significant improvement in knee function scores. Abnormal tracking remained in two patients (4.8%).
conclusionThe modified 'three-in-one' surgical procedure is effective and safe in treating habitual dislocation in adolescents.
