The effect of preoperative membranous urethral length on likelihood of postoperative urinary incontinence after robot-assisted radical prostatectomy.

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
backgroundUrinary incontinence after radical prostatectomy affects many men. In addition to surgical and patient factors, longer preoperative membranous urethral length (MUL) has been suggested to be associated with improved postoperative urinary continence outcomes. Here, we assess the association of preoperative MUL and the risk of persistent postoperative urinary incontinence after robot-assisted radical prostatectomy (RARP) for prostate cancer on extended follow-up.
methodsAll participants underwent RARP at the University of California, San Francisco between 2000-2018. Patients were excluded if preoperative MRI-measured MUL was not performed by a radiologist. A single, blinded urologist remeasured MUL retrospectively. Logistic regression models examined associations between radiologist- and urologist-measured MUL and likelihood of persistent incontinence post-RARP by two definitions: strict incontinence (>0 pad/day) and social incontinence (>1 pad/day).
resultsIn 251 men with a median follow-up of 42 months (IQR 29-76), the median MUL measurements were 14 mm ([IQR 12-17], radiologist) and 15 mm ([IQR 12-18], urologist) with poor agreement (interclass correlation coefficient 0.34). On logistic regression, urologist-measured longer MUL was associated with lower likelihood of strict incontinence within 6 months (odds ratio [OR] 0.87; 95% confidence interval [CI] 0.81-0.94) and 12 months (OR 0.90; 95% CI 0.82-0.98) and social incontinence within 6 months (OR 0.93; 95% CI 0.86-1.00) and 12 months (OR 0.84; 95% CI 0.74-0.95). Radiologist-measured longer MUL was associated with lower likelihood of strict incontinence within 6 months (OR 0.93; 95% CI 0.87-1.00) and social within 12 months (OR 0.87; 95% CI 0.77-1.00). MUL was not associated with likelihood of strict or social incontinence within 24 months.
conclusionPreoperative MRI-measured MUL was not associated with urinary incontinence after 12 months post-RARP. Poor agreement between radiologists' and urologist's measurements supports standardizing MUL measurements to establish the likelihood of early incontinence.
