Evaluation of isolated urinary stress incontinence according to the type of levator ani muscle lesion using 3/4D transperineal ultrasound 36 months post-partum.
Observational study in International urogynecology journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
introductionVaginal delivery can lead to pelvic floor disorders. Many authors have described pelvic floor injuries that can predict future defects such as urinary incontinence and pelvic organ prolapse. We propose the assessment of urinary stress incontinence and its association with levator ani muscle (LAM) microtrauma (>20% in the levator hiatus area during Valsalva) and macrotraumas (avulsion) identified by 3/4D transperineal ultrasound (3D-TpUS) 36 months post-partum. MATERIALS AND
methodsThis was a prospective observational study including 168 nulliparous women. All patients included were nulliparous with singleton gestation in cephalic presentation, at ≥37 weeks and were recruited on the first day after delivery. Thirty-six months after delivery, 3D-TpUS was carried out to identify LAM lesions (macro or micro). Clinical assessment of urinary stress incontinence (USI) was based on the ICIQ-UI-SF test; a simple stress test and urodynamic test were carried out in the same visit.
resultsA total of 105 nulliparous women were studied (51 spontaneous deliveries [SpD] and 54 vacuum-assisted deliveries [VD]). Microtraumas were identified in 35.3% of SpD and 20.4% of VD. Macrotraumas (avulsion) were identified in 9.8% of SpD and 35.2% of VD (p = 0.006). No differences were found in USI between study groups or in relation to the identification of LAM defects (19.2% in the no lesion group, 25% in the macrotrauma and 13.8% in the microtrauma groups; p = not significant). Nor were significant differences found in the results from the different study groups in the International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form (ICIQ-UI SF) test (12.7±2.2 in the no lesion group, 12.5±4.2 in the macrotrauma and 13.25±4.8 in the microtrauma groups; p = NS).
conclusionNo difference was observed in USI between patients with and without LAM lesions (microtrauma or macrotrauma) 36 months post-delivery.
