Parity: a risk factor for decreased pelvic floor muscle strength and endurance in middle-aged women.
Article in International urogynecology journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
introduction and hypothesisThe incidence of pelvic floor muscle (PFM) dysfunction increases rapidly with menopause and aging. Despite the raised magnitude and prevalence of pelvic floor disorders in middle-aged women, the risk factors underlying PFM dysfunction still remain to be identified. PFM function can be clinically measured as the maximum strength and endurance using manometry. The aim of this study was to evaluate PFM function in terms of strength and endurance by perineometer and to assess the risk factors that decrease PFM strength and endurance in middle-aged women.
methodsThis was a cross-sectional study. Overall, 125 parous women (age 40-60 years) completed the study. A questionnaire was used to collect information on several demographic and obstetric variables. The Peritron perineometer measured PFM strength and endurance. Multiple linear regression analysis was used to evaluate the effects of sociodemographic variables on PFM function.
resultsBoth average strength of PFMs and maximum muscle strength significantly reduced as the number of parity increased. Average and maximum strength of PFMs showed a significant difference between women with parities of two and one (β = -0.435, p < .001; β = -0.441, p < 0.001, respectively). Both were even more influenced in women with parity of three (β = -0.503, p < .001; β = -0.500, p < .001). However, PFM endurance did not decrease with increasing parity number until the parity of two; however, it decreased in women with parity of three (β = -0.302, p < 0.05).
conclusionParity appeared to have a dominant influence on weakness of PFM, and strength was more significantly associated with parity than endurance in middle-aged women.
