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
objectiveTo compare intrarenal pelvic pressure profiles and clinical outcomes between the leg-split-free lateral decubitus position and the conventional lithotomy position during flexible ureteroscopy with a negative-pressure aspiration sheath.
methodsA prospective study was conducted at Peking University People' s Hospital among patients undergoing unilateral flexible ureteroscopy with a negative-pressure aspiration sheath from January 2024 to December 2025. Participants were allocated into two groups according to surgical positioning: Leg-split-free lateral decubitus group and conventional lithotomy group. An intelligent, pressure- and temperature-controlled flexible ureteroscopy system was employed to continuously monitor intrapelvic pressure and temperature throughout the procedure. The incidence, duration, and clinical implications of intrapelvic hypertension were compared between the two groups.
resultsA total of 40 patients were enrolled, 20 in each group. No statistically significant differences were observed between the groups in baseline characteristics, including gender, age, stone diameter, stone number, stone location, or degree of hydronephrosis (all
conclusionThis prospective exploratory study suggests that compared with the lithotomy position, the leg-free lateral decubitus position may be more conducive to maintaining lower intrapelvic pressure and temperature during the operation and is associated with a higher stone clearance rate postoperatively. However, these findings still need to be verified by large-sample, multi-center, randomized controlled trials.
