Pelvic floor function and morphological abnormalities in primiparas with postpartum symptomatic stress urinary incontinence based on the type of delivery: a 1:1 matched case-control study.
Article in International urogynecology journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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 aim of this study was to assess pelvic floor muscle (PFM) morphology and function in primiparas with postpartum symptomatic SUI after different types of delivery.
methodsRetrospective analyses were carried out with individuals with postpartum symptomatic stress urinary incontinence (SUI). Among the women screened in our center from January 2018 to December 2019, participants were divided into elective cesarean section (eCS) and spontaneous vaginal delivery (sVD) groups, while being matched 1:1 on age (±5 years), body mass index (BMI; ±0.5 kg/m
resultsA total of 78 matched pairs were recruited based on delivery mode. Regarding functional differences, both fast-twitch and slow-twitch fiber strengths in the eCS group were significantly higher than those in the sVD group, but PFMs were more hyperactive in the eCS group. Regarding morphometric differences, the retrovesical angle (RVA) and bladder neck position were not significantly different in the resting state between the two groups, nor was the RVA during the Valsalva maneuver (eCS group: 130.68 ± 17.08°, sVD group: 136.33 ± 23.93°), p > 0.05. There were differences in bladder neck descent (BND; eCS group: 16.51 ± 7.55 mm, sVD group: 23.92 ± 8.47 mm) and urethral rotation angle (URA; eCS group: 37.53 ± 26.05°, sVD group: 59.94 ± 25.87°), all p < 0.05. BND showed a negative correlation with PFM strength, p < 0.05. URAs and RVAs showed no correlation with PFM strength, p > 0.05.
conclusionPelvic floor muscle function disorder, hyperactivity, and instability also occurred after eCS, which resulted in postpartum symptomatic SUI. The effects of sVD compared with eCS on abnormalities in the lower urinary tract were related to bladder neck and urethral hyperactivity, without an RVA increase.
