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: Periacetabular osteotomy (PAO) is the standard treatment for developmental dysplasia of the hip (DDH). Although intra-articular pathology such as labral tears is common, the benefit of routinely combining PAO with hip arthroscopy is uncertain. Evaluating the frequency and indications for arthroscopy after isolated PAO is key to determining whether PAO alone adequately addresses intra-articular disease and to guide surgical decision-making. Methods: This retrospective cohort study included 59 patients who underwent PAO for symptomatic DDH between January 1, 2018, to October 1, 2023, at a single tertiary academic center. Those without a minimum of one-year follow-up were contacted by phone for data collection. Preoperative imaging and postoperative outcomes were reviewed. A follow-up phone survey was conducted at a median of 2.6 ± 1.5 years postoperatively. The primary outcome was the incidence of subsequent hip arthroscopy. Secondary outcomes included persistent pain, imaging findings, and patient-reported interest in future surgery. Comparative analyses were performed between those who did and did not undergo arthroscopy. Results: A total of 59 patients were included, with 53 (89.8 %) successfully completing phone interviews. The mean preoperative LCEA was 15.0° ±6.8, and the mean postoperative LCEA was 28.8° ±2.1, with an average change of 14.2°. Labral tears were identified in 31 of 51 (60.7 %) patients who had preoperative MRIs. Hip arthroscopy was performed in 4 (6.8 %) patients postoperatively. Of the patients contacted, 47 (88.7 %) reported no interest in future arthroscopy, while 2 (3.8 %) expressed potential interest. The 6 patients not reached had no documented evidence of follow-up surgery or continued symptoms. Conclusion: Preoperative labral tears are common in patients undergoing PAO, but only a small percentage require subsequent arthroscopic intervention based on our findings. Larger studies are needed to further assess the role of arthroscopy in DDH.
