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
Objective: The objective of this work is to evaluate the safety and short-term outcomes of laparoscopic dismembered pyeloplasty (LDP) for ureteropelvic junction obstruction (UPJO) in children, based on a single-surgeon experience using a transabdominal suspension technique. Methods: We retrospectively analyzed children with UPJO between January 2023 and October 2024 who underwent transperitoneal LDP with a transabdominal suspension maneuver performed by a single surgeon. The diagnosis was confirmed by ultrasonography and magnetic resonance urography. The outcomes were operative time, complications, hospital stay, and postoperative hydronephrosis reduction, assessed by ultrasonography at least 3 months after the operation. Results: A total of 60 children with a mean age of 58.5 months (range: 6-168 months) underwent surgery during the study period; of these, 47 were boys. The mean operative time was 140 min (range: 120-200 min). No open conversions or major complications occurred. The mean hospital stay was 3.5 days. The median pelvic diameter decreased from 35.6 mm (range: 25-50 mm) preoperatively to 13.5 mm (range: 8-22 mm) postoperatively ( Conclusions: Transperitoneal laparoscopic dismembered pyeloplasty is a safe and effective option in the treatment of UPJO, and a transabdominal suspension technique may facilitate the procedure.
