Pelvic organ support several years after a first birth.
Article in International urogynecology journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 hypothesisFemale pelvic organ prolapse is highly prevalent and childbirth has been shown to be an important risk factor. The study was carried out to observe if pelvic organ support deteriorates over time following a first birth.
methodsThis is a retrospective review using archived data sets of women seen in the context of two prospective perinatal imaging studies. All subjects had undergone a standardised interview, a clinical examination and 4D translabial ultrasound, 3 months and 2-5 years post-partum. Main outcome measures were pelvic organ descent and hiatal area at maximum Valsalva manoeuvre. Means at the two time points were compared using paired Student's t test. Predictors of change over time in continuous variables were explored using linear modelling methods.
resultsA total of 300 women had at least two postnatal follow-ups. They were first seen on average 0.39 (SD 0.2, range 0.2-2.1) years and again 3.1 (SD 1.5, range 1.4-8) years after the index delivery, with a mean interval of 2.71 (SD 1.5, range 0.7-7.7) years, providing a total of 813 (300 × 2.71) woman-years of observation. On univariate analysis, there was a significant decrease in mobility over time of the bladder neck, bladder, and rectal ampulla (P = < 0.004) and hiatal area (P = 0.012). The degree of improvement was less marked in women with levator avulsion.
conclusionsA significant reduction in pelvic organ descent and hiatal area was noted over a mean of 2.7 years after a first birth.
