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: To evaluate the clinical utility of robot-assisted laparoscopic resection for large pheochromocytomas via the renal surface plane, using the fatty fissure as an anatomical landmark. Methodology: This retrospective study included 60 patients with large adrenal pheochromocytomas treated at The Affiliated Hospital of Hebei University (January 2023-December 2024), randomized into two groups (n=30 each). The study group underwent the landmark-guided procedure, while the control group received conventional posterior retroperitoneal robot-assisted laparoscopic surgery. Perioperative parameters (operation duration [DoO], intraoperative blood loss [IBL], drain removal time [DRT], postoperative hospital stay [LoPHS]) and complications (intraoperative hemodynamic instability [IHDI], vasoactive agent use, ICU transfer rate, adrenal crisis, arrhythmia, stress ulcers) were compared. Results: The study group showed significantly shorter DoO, LoPHS and DRT (P=0.00), lower IBL (P=0.00), reduced IHDI incidence, vasoactive agent use and ICU transfer rate (P<0.05 each), and a lower overall postoperative complication rate (P=0.04) versus the control group. Conclusion: Fatty fissure-guided robot-assisted laparoscopic adrenalectomy via the renal surface plane improves anatomical guidance, reduces IBL, shortens operative and recovery time, and lowers complications for large pheochromocytomas, representing a safe, effective option for wider clinical use.
