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: Prostate cancer is a common malignant tumor in the male urogenital system, and laparoscopic radical prostatectomy (LRP) is the standard surgical procedure for early-stage patients. However, postoperative urinary incontinence remains a major complication. The membranous urethra and its surrounding sphincters play a critical role in urinary continence, but the impact of their preserved length on postoperative recovery of urinary continence function remains unclear. Objective: To investigate the effect of the preserved length of the membranous urethra during LRP on early and long-term recovery of urinary continence function in patients. Methods: A retrospective analysis was conducted on 160 patients who underwent LRP from March 2023 to June 2024. The patients were divided into a long-segment group (preserved length ≥15 mm, 90 cases) and a short-segment group (preserved length <15 mm, 70 cases) based on the preserved length of the membranous urethra. The International Continence Society criteria were used to evaluate the urinary continence recovery rate (≤1 pad/day) at 1, 3, 12, and 24 months postoperatively, and differences between the two groups were compared. Results: Baseline characteristics were comparable between long-segment (≥15 mm, Conclusion: Preserving the length of the membranous urethra ≥15 mm during LRP can significantly promote the recovery of early and long-term urinary continence function, providing a basis for precise surgical operations in clinical practice. Future studies with larger sample sizes and longer follow-up periods are needed for validation.
