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: Arthroscopic loose-body removal and synovectomy are recommended for the treatment of knee synovial chondromatosis (SC). However, there are limited data on clinical outcomes and survivorship after arthroscopic treatment for knee SC. Purposes/Hypothesis: The purpose was to evaluate the clinical outcomes and survivorship of arthroscopic loose-body removal and synovectomy in patients with knee SC, as well as to investigate the potential effect of concomitant chondral lesions on these outcomes. It was hypothesized that arthroscopic treatment for knee SC could yield satisfactory clinical outcomes, with concomitant chondral lesions negatively affecting clinical efficacy. Study Design: Case series; Level of evidence, 4. Methods: A consecutive cohort of patients diagnosed with knee SC and treated with arthroscopy between 2016 and 2022 was included in the study. Patient-reported outcomes (PROs) were collected preoperatively and at the final follow-up, including the Knee injury and Osteoarthritis Outcome Score, the subjective International Knee Documentation Committee (IKDC) score, the Lysholm score, and the visual analog scale for pain score. Data on arthroscopic findings, patient satisfaction, complications, and survivorship rates were also documented. The percentage of patients achieving the minimal clinically important difference (MCID) was calculated. Clinical outcomes were then compared between patients with and without chondral lesions identified during arthroscopy. Results: A total of 51 patients (54 knees) were included in the study, with a mean age at surgery of 42.3 ± 14.7 years and a mean follow-up period of 5.6 years. All PROs showed significant improvements at the final follow-up ( Conclusion: Arthroscopic treatment for knee SC yields favorable clinical outcomes with symptom relief and functional improvement. However, there remains a risk of recurrence and the need for reoperation. Additionally, patients with concomitant chondral lesions could achieve clinical outcomes and survivorship comparable to those of patients without chondral lesions.
