Signs of damage in pelvic floor muscles at the end of pregnancy in rabbits.
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 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 hypothesisTemporary effects to pelvic floor muscles are linked to impairments in micturition, particularly stress urinary incontinence (SUI), during pregnancy. We hypothesize that bulbospongiosus (Bsm) and pubococcygeus (Pcm) are differently damaged in primigravid and primiparous rabbits.
methodsTwenty-four rabbits allocated evenly (n = 6) into nulliparous, pregnant, and primiparous groups on postpartum days 3 (P3) and 20 (P20) were used to evaluate the myofiber cross-sectional area (CSA), β-glucuronidase activity, and anti-3-nitrotyrosine (anti-3-NTyr) immunoreactivity in Bsm and Pcm muscles. Appropriate statistical tests were done to determine significant differences among groups (P ≤ 0.05).
resultsThe average CSA of Bsm was not significantly different, albeit a high percentage of myofibers was enlarged in late-pregnant and primiparous rabbits on P3; β-glucuronidase activity and indirect parameter of muscle damage was also higher. These variables did not change in the Pcm muscle during the different reproductive stages. In contrast, the 3-NTyr immunoreactivity, an indicator of oxidative damage, was increased on P3 for Pcm myofibers and P20 for myofibers of both muscles.
conclusionsOur findings demonstrate reliable signs of damage to Bsm and Pcm muscles in young female rabbits passing different reproductive stages. Damage to the Bsm muscles as detected at the end of pregnancy persisted after delivery. This was not the case for Pcm muscles, in which damage seems to appear after delivery.
