The Posterior Urethrovesical Angle in Continent and Incontinent Women Before and After a Treadmill Run.

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
introduction and hypothesisThe posterior urethrovesical angle (PUVA) is larger in women with general stress urinary incontinence (SUI) than those without. We aimed to determine whether baseline PUVA or changes in PUVA after a treadmill run differ between runners with and without running-induced SUI (RI-SUI). Among runners with RI-SUI, we also compared those who leaked urine during a treadmill protocol and those who did not.
methodsWe recruited female runners with and without RI-SUI. Ultrasound imaging was used to measure bladder volume (BV) in supine (transabdominal) and PUVA in standing (transperineal), before and after a standardized treadmill run. Separate general linear models (α = 0.05) included PUVA as the dependent variable, time (pre- vs post-run) and group (continent vs incontinent) as independent variables, and baseline BV and PUVA, age and parity as covariates, first comparing runners with and without RI-SUI then, among runners with RI-SUI, comparing those who leaked urine and those who did not.
resultsOf the 96 participating runners, data from 85 (28 with RI-SUI, 57 without) were analyzed after excluding images with poor PUVA visualization. PUVA increased after running (continent 120.4 ± 15.8º to 125.6 ± 15.7º; RI-SUI 123.8 ± 15.6º to 127.0 ± 17.1º) with no significant between-group differences or interactions (time × group F(1,1) = 1.32, p = 0.25, partial η
conclusionsAlthough proximal urethral support is reduced in women after a treadmill run, the PUVA does not appear to be independently associated with RI-SUI.
