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
purposeThis study aims to describe the differences in the urethral motion profile (UMP) of primiparous and multiparous women immediately postpartum.
methodsThis prospective study recruited 65 women (29 primiparous, 36 multiparous) one-seven days postpartum. The patients underwent a standardised interview and two-dimensional translabial ultrasound (TLUS). To evaluate the UMP, the urethra was manually traced and divided into five segments with six equidistant points. The mobility vector (MV) for each point was calculated as [Formula: see text]. A Shapiro-Wilk test was conducted to test normality. An independent t-test and a Mann-Whitney test were conducted to express differences between the groups. The Pearson correlation coefficient was used to determine the relationships among MVs, parity and confounders. Finally, a univariate generalised linear regression analysis was performed.
resultsMV1-MV4 were found to be normally distributed. A significant difference for all MVs, except for MV5, was demonstrated between parity groups (MV1: t = 3.88 (p < .001), MV2: t = 3.82 (p < .001), MV3: t = 2.65 (p = .012), MV4: t = 2.54 (p = .015), MV6: U = 150.00 (exact sig. two tailed = .012)). A strong-to-very strong mutual correlation was observed between MV1 to MV4. The univariate generalised linear regression showed that parity can predict up to 26% of urethral mobility.
conclusionThis study shows that multiparous women have significantly higher urethral mobility compared to primiparous women in the first week postpartum, with the most significant effect observed in the proximal urethra.
