Impact of body mass index on outcomes after radical cystectomy: A retrospective Australian cohort study.

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
Objectives: This study aimed to assess the association between body mass index and perioperative outcomes and survival after radical cystectomy for bladder cancer in an Australian cohort. Subjects/patients and methods: We conducted a retrospective single-centre study of patients undergoing radical cystectomy between 2008 and 2021. Preoperative body mass index (BMI) was analysed categorically and continuously. Outcomes included overall survival (OS), Clavien-Dindo grade ≥2 complications and length of hospital stay. Survival was analysed using Kaplan-Meier methods and multivariable Cox regression adjusting for age, sex, tumour stage, nodal status and chemotherapy. Restricted cubic splines were used to explore non-linear associations. Results: The cohort comprised 135 patients (median age 70 years; median BMI 27.2 kg/m Conclusion: Overweight BMI was associated with improved survival following radical cystectomy, while obesity was linked to greater perioperative morbidity. These findings are consistent with the obesity paradox and underscore the limitations of BMI alone for perioperative risk stratification.
