Serum vitamin D levels in females with urinary incontinence: a meta-analysis of observational trials.
Synthesis in International urogynecology journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 hypothesisThe association of vitamin D deficiency with female urinary incontinence is unclear.
methodsA systematic review of English and non-English articles was conducted. All observational studies in databases including PubMed, EMBASE, the Cochrane Library Trials Register, and Google Scholar were searched until 5 October 2020. Additional studies were identified by contacting clinical experts and searching the bibliographies and abstracts of the compiled articles. Search terms included urinary incontinence and vitamin D. Article data, including study quality indicators, were independently extracted by two authors using predefined data fields.
resultsTwo cohort studies, four case-control studies and five cross-sectional studies were included in the qualitative synthesis. Two cohort studies and one cross-sectional study, with a total of 2501 females, were included in the meta-analysis. Heterogeneity among the three studies was not observed (I2 = 0.0%, P = 0.69). All pooled analyses were based on fixed-effects models. No difference in vitamin D level was observed between the urinary incontinence group and the control group (mean difference 0.07 ng/ml; 95% confidence interval [CI] -0.57-0.72, P = 0.81, I2 = 0%).
conclusionsOur meta-analysis revealed that adult females with urinary incontinence did not have lower serum vitamin D levels than control females.
