The impact of body mass and posterior adiposity indices in robotic adrenalectomy.

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
backgroundRobotic adrenalectomy is performed via transabdominal (TA) or retroperitoneoscopic (RP) approaches, but the impact of body mass index (BMI) on robotic adrenalectomy outcomes in either approach is unclear. Posterior Adiposity Index (PAI), predictive of operative time in RP adrenalectomy, remains unevaluated with the robotic platform. This study assessed the impact of patient BMI and PAI on surgical outcomes in patients undergoing either TA or RP robotic adrenalectomy.
methodsThis was a single-institution retrospective cohort study of adult patients who underwent robotic adrenalectomy from 5/1/2018 to 6/17/2024. Patients were analyzed by approach and BMI. The primary outcome was operative time. Secondary outcomes included estimated blood loss (EBL), length of stay (LOS), and complications within 30 days. The correlation of operative time to PAI, BMI, and patient characteristics was assessed.
results149 patients (age 55 yrs. [IQR:42,66], 70% female) underwent 98 TA and 51 RP robotic adrenalectomies. Patients who underwent TA robotic adrenalectomies had larger nodules, higher BMI, and greater EBL; operative time, LOS, and complications were similar. Patients with elevated BMI (BMI ≥ 25) had similar preoperative characteristics to those with normal BMI (BMI < 25); they had longer operative times (129 min [107, 156] vs. 118 [90, 134], p = 0.045) and LOS (1 [1,1] vs 1 [1,1] p = 0.015) including two patients with 8-day LOS, but similar EBL (5 [5,10] vs. 10 [5,23], p = 0.828) and complication rates (15% vs 5%, p = 0.477). Among TA, but not RP, patients, BMI weakly correlated with operative time (
conclusionThis retrospective cohort study evaluating the impact of BMI and PAI on surgical outcomes in patients undergoing robotic adrenalectomy demonstrated that while elevated BMI (BMI ≥ 25) appears to prolong TA robotic adrenalectomy, PAI is not predictive of operative time in RP robotic adrenalectomy.
