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

Purpose: This study aims to investigate the differences in pelvic floor dysfunction (PFD) and diastasis recti abdominis (DRA) between primiparous and second-parous females with known risk factors controlled. Patients and Methods: 49 primiparous and 49 age-matched second-parous postpartum after spontaneous vaginal delivery were included between October and December 2023. Independent variables include weight, height, body mass index (BMI), fetal weight, gestational weight gain (GWG). Main outcome measurements include vaginal resting pressure (VRP) and maximum voluntary contraction pressure (MVCP) indicating pelvic floor muscle strength, the stage of anterior (APOP) and posterior pelvic organ prolapse (PPOP) and inter-recti distance (IRD) indicating DRA. Independent Results: No significant differences were found in terms of vaginal pressure measurements between two groups (VRP: t (96) = 0.07, Conclusion: Second-parous females at similar age are more likely to experience PPOP than primiparous group after spontaneous vaginal delivery. Greater public attention with plausible actions should be taken for second-parous female group to prevent more severe postpartum pelvic floor dysfunction.
