Is Vaginal Laxity Associated with Vaginal Parity and Mode of Delivery?
Observational study in International urogynecology journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 hypothesisVaginal laxity (VL) is a common symptom of pelvic floor dysfunction. Although VL has become a frequent topic for research in the last decade, its pathogenesis is still not well understood. The objective was to determine whether vaginal parity or mode of delivery is associated with vaginal laxity.
methodsThis was a retrospective observational study involving women seen in a tertiary urogynecology clinic between May 2016 and November 2018 with symptoms of pelvic floor dysfunction. Patients underwent a standardized interview, clinical examination (POP-Q), and four-dimensional (4D) pelvic floor ultrasound (PFUS). Data regarding vaginal parity and the mode of delivery were based on patient-reported information. Archived 4D-PFUS volumes were analyzed offline to evaluate levator hiatal area on Valsalva.
resultsData from 1,051 patients were analyzed. VL was reported by 236 women (23%) who were younger on average (mean age 54 vs 59 years, p < 0.001) and less likely to be menopausal (530 out of 815 [65.0%] vs.129 out of 236 [54.7%]), p = 0.004]. Symptoms of prolapse were much more common in the VL group (214 out of 236 [91%] vs 316 out of 815 [39%], p = < 0.001) and on imaging mean levator hiatal area (HA) on Valsalva was larger (31 vs 26 cm
conclusionsVaginal laxity was found to be more prevalent in vaginally parous women. This effect seems to be largely attributable to the first delivery. Instrumental delivery was not shown to increase association with VL compared with normal vaginal delivery.
