Antenatal and postnatal assessment of pelvic floor muscles in continent and incontinent primigravida women.
Article in International urogynecology journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 hypothesisReduced pelvic floor muscle (PFM) strength and thickness are considered critical factors in pregnancy-related stress urinary incontinence. Various methods have been evaluated for the measurement of these two factors, but validity needs to be well established. The objective was to assess the strength and thickness of pelvic floor muscles of continent and incontinent primigravida women using the digital method and transperineal ultrasound, and to study the correlation between the two methods.
methodsAssessment of pelvic floor muscle strength and thickness using digital assessment and transperineal ultrasound antepartum and postpartum in 100 primigravida women.
resultsA total of 100 primigravida women with 46 in the study group (incontinent) and 54 in the control group (continent) were assessed. PFM strength was lower in incontinent women, with a score of 3 or less in 82.61% (38 out of 46) compared with a score of 4 or more in 98.15% of continent women (53 out of 54; p < 0.0001) antenatally, as well as postnatally, with 81.25% of the incontinent women (26 out of 32), with a score of 3 or less compared with 100% of continent women (24 out of 24), with a score of 4 or more (p < 0.0001). The PFM thickness in the incontinent group compared with the continent group at relaxation was 5.94 ± 0.51 mm and 6.64 ± 0.26 mm (p < 0.0001) antenatally and 5.98 ± 0.55 mm and 6.69 ± 0.23 mm (p < 0.0001) postnatally; at contraction it was 7.29 ± 0.56 mm and 8.70 ± 0.24 mm (p < 0.0001) antenatally and 7.39 ± 0.56 mm and 8.77 ± 0.20 mm (p < 0.0001) postnatally. The Pearson correlation coefficient for the two methods during the antenatal and postpartum periods was 0.864 and 0.743 respectively, suggestive of a positive correlation between the two methods.
conclusionsPelvic floor muscle strength, as well as thickness, is significantly lower among the incontinent group than among the continent group, both during antenatal and during the postnatal period.
