Article in Ultrasonography (Seoul, Korea), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07183800 (Does a 10-minute Trampoline Protocol Induce Urine Leakage or Changes in Pelvic Morphometry Among Females Who Report That They do Not Experience Symptoms of Urinary Incontinence?), which is not on this map.

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.

Abstract

purposeThe aim of this study was to explore differences in the bladder neck configuration and segmental urethral mobility during the cough stress test (CST) in the supine and standing positions between women with and without stress urinary incontinence (SUI).

methodsThis prospective study included 100 control women and 100 incontinent women who had a CST with transperineal ultrasonography. The bladder neck configuration and urethral mobility were described in terms of urethral funneling, bladder neck descent (BND), retrovesical angle (RVA), urethral rotation angle, and urethral mobility at six points along the urethra (vectors 1 to 6). The two groups' ultrasound findings in the two positions were compared.

resultsValid data were collected from 78 control women and 90 women with SUI. Significant differences were found in age and body mass index between the two groups (P<0.01). Urethral funneling was found in 33 women (36.7%) with SUI and five continent women (6.4%) and altered little in the standing position. In the standing position, the mean RVA significantly increased (160° to 179°, P<0.001) in the SUI group; The mean vector of points 1 to 6 significantly increased in the control group (all P<0.001). The RVA, BND, and vectors 1 to 4 were significantly greater (all P≤0.01) in women with SUI than without, in both positions.

conclusionUrethral funneling was an intrinsic anatomical characteristic relative to SUI. Weak upper- and mid-urethral support and an unstable connection between the trigone and proximal urethra were the anatomical signs of SUI.
