Article in International urogynecology journal, 2020. 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 hypothesisOrgasm and other sexual responses such as pain, arousal and lubrication may be mediated by nerve fibers and vessels in the lamina propria and muscularis of the vaginal wall, in which case the number of nerve fibers and vessels would be associated with sexual functions. The aim of the study is to map the distribution of nerves and vessels in the anterior vaginal wall along the paraurethral region in a systematic fashion.
methodsSpecimens were taken from women with anterior vaginal wall prolapse undergoing colporrhaphy anterior repair. All specimens were mapped in a standard way starting 15 mm proximal to the external urethral orifice. Selected blocks of samples were immunohistochemically stained: actin, smooth muscle Ab-1 and S100 Protein Ab-1. The numbers of microvessels and nerves in the lamina propria and muscularis were counted in five consecutive high-power fields of a light microscope. Pairwise comparisons of proximal, distal, right and left paravaginal microvessel and nerve fiber density were analyzed with paired-sample t-test or Wilcoxon signed-rank test.
resultsVaginal nerve fibers in the lamina propria and muscularis have a fairly even distribution in the anterior vaginal wall. Vaginal small vessel vascularization and microvascularization are also evenly distributed, with no concentrated site along the paraurethral region of the anterior vaginal wall.
conclusionsNerve fiber, nerve bundle, microvessel and small vessel densities in the lamina propria and muscularis were fairly regular, with no concentrated site on the paraurethral region of the anterior vaginal wall.
