Article in International urogynecology journal, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04525846 (A Comparison of Urinary Incontinence During Third Trimester of Nulliparous on Pelvic Floor Muscle Training in Rajavithi Hospital), which is not on this map. Cited by 49 papers, 7 of them syntheses that pooled it.

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.

Abstract

introduction and hypothesisWe sought to characterize risk factors of urinary incontinence (UI) during pregnancy and the postpartum period in primiparous women in China.

methodsWe enrolled 10,098 women from the seven regions of China ≥28 weeks' gestation from September 2007 to May 2009 and administered the Bristol Female Lower Urinary Tract Symptoms questionnaire to estimate the presence of different types of UI during late pregnancy (37 to 42 weeks' gestation) and at 6 weeks and 6 months postpartum. We also collected details of pregnancy and childbirth and demographic data. McNemar's test, multinomial logistic regression models, and binary logistic regression models were used.

resultsMultivariable analysis revealed six independent risk factors for SUI: age, more frequent exercise, alcohol consumption, higher body mass index, larger waist circumference, and history of constipation. For those with no UI in late pregnancy, 3.7% and 3.0% developed new cases at 6 weeks and 6 months postpartum, respectively. Risk factors for UI at 6 months were frequent exercise, rural residence, perineal laceration, and lateral episiotomy. Prevalence of all UI was 26.7% in late pregnancy, 9.5% at 6 weeks postpartum, and 6.8% at 6 months postpartum. Most cases were stress urinary incontinence (18.6%, 6.9%, and 5.0%, at the respectively times).

conclusionsRates of UI in primiparous women in China are consistent with those reported elsewhere. Rural location, frequent exercise, and birth-related injuries are risk factors for UI at 6 months postpartum.
