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
introductionThis study aimed to investigate the impact of peritoneal patency during extraperitoneal laparoscopic radical prostatectomy (eLRP) on perioperative and postoperative outcomes.
methodsBetween May 2018 and March 2025, 255 patients who underwent eLRP were retrospectively evaluated. Patients without peritoneal opening were classified as group 1 (n=223), while those with peritoneal opening were classified as group 2 (n=32). Demographic data, operative time, complication rates, and complication grades based on the Clavien-Dindo classification were analyzed. Logistic regression analysis was performed to identify associated risk factors.
resultsA history of abdominal surgery was significantly more common in group 2 (p<0.001) and the mean operative time was also significantly longer in this group (p<0.001). Although the overall complication rate was higher in group 2 (37.5% vs. 24.2%), the difference was not statistically significant (p=0.131). Multivariate analysis revealed that a history of abdominal surgery, operative time >180 minutes, and estimated blood loss >150 ml were significantly associated with postoperative complications; however, peritoneal opening was not identified as an independent risk factor (p=0.113).
conclusionsAlthough peritoneal opening may introduce technical challenges that compromise the advantages of the extraperitoneal approach, it does not significantly affect postoperative complication rates. With sufficient surgical experience, it appears to be a manageable intraoperative event.
