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

backgroundPelvic floor disorders encompass several problems resulting from inadequacies in the pelvic floor muscles (PFMs), especially after childbirth. Obstetric anal sphincter injury (OASIS) is a possible complication of vaginal birth that may significantly affect quality of life. Factors related to the pregnant woman, childbirth, and the newborn can increase the risk of developing OASIS.

methodsThis study encompasses a prospective, randomized clinical trial design with parallel groups. Women diagnosed with OASIS are recruited within 60 days of giving birth. The control group receives standard postpartum care, and the intervention group receives standard care plus a PFMs training program for 12 weeks. Participants are assessed in three in-person and two online sessions throughout the study. The study is conducted at a single center. The primary outcome will be pelvic floor muscle function assessed using the PERFECT scheme, dynamometry, and surface electromyography. Secondary outcomes will include pelvic floor dysfunction symptoms (Australian Pelvic Floor Questionnaire), self-efficacy, and subjective cure. Data will be analyzed using intention-to-treat principles, with appropriate parametric or non-parametric tests. DISCUSSION: This study aims to investigate the effect of PFMs' training in postpartum women with OASIS on PFMs' function and pelvic floor disorder symptoms. PFMs' training is expected to improve PFMs' function, reduce pelvic floor disorder symptoms, and provide an effective therapeutic option for postpartum women with anal sphincter injuries. This study provides significant results on the effectiveness of PFMs' training as an intervention for women with OASIS, contributing to improving the quality of life of these patients. This study will provide evidence on the effectiveness of pelvic floor muscle training in postpartum women with OASIS and may contribute to improving clinical management in this population.
