Impact of sex disparities on laparoscopic adrenalectomy outcomes: a coarsened exact matching study.
Article in BMC urology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveIt is unclear how sex disparities affect surgical outcomes following retroperitoneal laparoscopic adrenalectomy (RLA). Therefore, we studied whether gender could affect RLA outcomes perioperatively.
methodsA retrospective study was performed involving consecutive cases underwent unilateral RLA for adrenal disease from January 2012 to December 2021. Coarsened exact matching (CEM) was applied to balance patient groups. Logistic regression analysis was performed to assess the impact of sex on prolonged operative time and increased intraoperative blood loss.
resultsA total of 569 patients who underwent RLA were included. After CEM, 112 patients were incorporated in each group. Operative time (male: 129.47 vs. female: 95.53, P < 0.001) and intraoperative blood loss (male: 123.39 vs. female: 101.61, P = 0.009) differed statistically significantly, while equal postoperative length of stay (LOS) (6.7 d vs. 6.8 d, P = 0.686), drainage tube removal time (3.0 d vs. 3.0 d, P = 0.231) and incidence of Clavien-Dindo grade ≥ 2 perioperative complications (8.0% vs. 7.1%, P = 0.801) was discovered. Moreover, the multivariable logistic regression analysis revealed that male was an independent risk factor for prolonged operative time (OR: 3.01, P < 0.001) and increased intraoperative blood loss (OR: 2.31, P < 0.001).
conclusionThe biologically male gender is associated with longer operative times and more blood loss during RLA, acting as an independent risk factor. Conversely, no disparity was observed in postoperative LOS or postoperative complications. These findings underscore the importance of sex-neutral care in RLA and the need for further research in diverse patient populations.
