Identification of risk factors for postpartum pelvic floor dysfunction in a Chinese population: a retrospective study.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo identify risk factors for postpartum pelvic floor dysfunction (PFD) diagnosed at 6 weeks after delivery in a Chinese population.
methodsThis retrospective study examined data from 828 postpartum women in China, collected from January 2020 to August 2021. Multivariate analyses were employed to identify factors associated with six outcomes of PFD, including anterior vaginal wall prolapse, posterior vaginal wall prolapse, uterine prolapse, stress urinary incontinence (SUI), and impaired type I and type II muscle fiber strength.
resultsA series of factors are considered to be associated with PFD. Cesarean delivery significantly reduced severe anterior vaginal wall prolapse risk (OR=0.426, P＜0.001). Age, overweight (BMI ≥24.9 kg/m²), macrosomia (birth weight ≥4000g), forceps-assisted delivery, and constipation significantly increased risks of anterior and posterior vaginal wall prolapse, uterine prolapse, and SUI (all OR>1, P<0.05). Twin pregnancy reduced type I (OR=0.430, P=0.013) and type II (OR=0.385, P=0.009) muscle fiber strength but increased risks of anterior vaginal wall prolapse, uterine prolapse, and SUI. Higher parity (two or more) was correlated with higher risks of anterior (OR=2.402, P<0.001) and posterior vaginal wall prolapse (OR=2.977, P=0.0003) and SUI (OR=1.726, P=0.001). Heavy physical labor was strongly associated with posterior vaginal wall prolapse (OR=6.285, P=0.008), uterine prolapse (OR=5.264, P=0.009), and SUI (OR=3.987, P=0.024). Underweight status (BMI<18.5 kg/m²) significantly increased risks of impaired type I (OR=0.173, P<0.001) and type II muscle fiber strength (OR=0.197, P=0.0003).
conclusionThis study identified significant PFD risk factors in a Chinese population, highlighting the importance of targeted prenatal, perinatal, and postpartum care to mitigate these risks. In addition to uncontrollable factors like mode of delivery, age, and parity, interventions targeting weight gain and fetal macrosomia during pregnancy and appropriate assisted delivery could mitigate the risks of PFD. Educational programs for pregnant women should emphasize a proper diet and lifestyle. For women with chronic constipation, clinical treatment should be carried out as soon as possible to avoid further aggravating the damage to the pelvic floor muscles.
