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.

2 · The registry

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 perineum stretches naturally during obstetrical labor, but it is unknown whether this stretch has a negative impact on pelvic floor outcomes after a vaginal birth (VB). We aimed to evaluate whether perineal stretch was associated with postpartum pelvic floor dysfunction, and we hypothesized that greater perineal stretch would correlate with worsened outcomes.

methodsThis was a prospective cohort study of primiparous women who had a VB. Perineal body (PB) length was measured antepartum, during labor, and 6 months postpartum. We determined the maximum PB (PBmax) measurements during the second stage of labor and PB change (ΔPB) between time points. Women completed functional questionnaires and had a Pelvic Organ Prolapse Quantification (POP-Q) system exam 6 months postpartum. We analyzed the relationship of PB measurements to perineal lacerations and postpartum outcomes, including urinary, anal, and fecal incontinence, sexual activity and function, and POP-Q measurements.

resultsFour hundred and forty-eight women with VB and a mean age of 24 ± 5.0 years with rare (5 %) third- or fourth-degree lacerations were assessed. During the second stage of labor, 270/448 (60 %) had perineal measurements. Mean antepartum PB length was 3.7 ± 0.8 cm, with a maximum mean PB length (PBmax) during the second stage of 6.1 ± 1.5 cm, an increase of 65 %. The change in PB length (ΔPB) from antepartum to 6 months postpartum was a net decrease (-0.39 ± 1.02 cm). PB change and PBmax were not associated with perineal lacerations or outcomes postpartum (all p > 0.05).

conclusionsPB stretch during labor is unrelated to perineal laceration, postpartum incontinence, sexual activity, or sexual function.
