1 · What the graph read from it

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.

2 · The registry

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

backgroundObesity is an increasing comorbidity in patients undergoing radical cystectomy. While robot-assisted radical cystectomy (RARC) has been widely adopted, evidence for its safety in overweight patients remains limited.

methodsWe retrospectively analyzed 337 consecutive patients who underwent RARC or open radical cystectomy (ORC) at a European tertiary center (2013–2024). Outcomes were stratified by body mass index (BMI) and assessed by regression and non-inferiority analyses.

resultsIn the presented cohort (135 normal-weight and 202 overweight patients) urinary-diversion patterns (continent vs. incontinent) did not differ by BMI or approach. RARC required longer operative times than ORC, but BMI itself had no independent effect. The length of stay (LOS) was shorter after RARC with BMI increasing LOS only in the ORC group. Adjusted models identified ORC as an independent predictor of prolonged stay. Non-inferiority of RARC in overweight patients was demonstrated for both length of stay (p = 0.044) and Clavien–Dindo-graded perioperative morbidity.

conclusionRARC delivers robust perioperative safety in overweight patients, maintaining non-inferiority for morbidity and LOS. These findings support the use of RARC as a standard approach to radical cystectomy, including in obese populations.
