Vitamin D Intake and Progression of Urinary Incontinence in Women.
Article in Urology, 2021. 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
objectiveTo determine if vitamin D intake is associated with reduced progression of urgency urinary incontinence (UI) in women.
methodsWe used the Nurses' Health Study (NHS) I and NHSII cohorts to evaluate the association of vitamin D intake with progression of urgency UI and mixed UI, from mild-moderate to severe symptoms, from 2004 to 2012 (NHS) and 2005-2013 (NHSII). Intake of vitamin D at study baseline was categorized and updated at the start of each 2-4 year follow-up period. Multivariable-adjusted relative risks (RRs) and 95% confidence intervals (95% CI) of progression to severe UI were estimated using Cox proportional hazard models.
resultsAt baseline, of the 20,560 older women (age range 58-73 years) in NHS I with mild/moderate urgency or mixed UI, 21% reported oral vitamin D intake of at least 800 IU per day. Among 12,573 middle-aged women (age range 42-59) in NHS II with mild/moderate urgency or mixed UI, 17% reported oral vitamin D intake of at least 800 IU daily. From 2004 to 2012, 4853 incident cases of urgency/mixed UI progression were identified among older women. From 2005 to 2013, 1378 incident cases of urgency/mixed UI progression were identified among middle-aged women. After multivariable adjustment, no significant associations between vitamin D intake and incidence of urgency/mixed UI progression were observed in either cohort (RR = 1.10, 95% CI 0.99-1.23 in older women, RR = 0.88, 95% CI 0.71, 1.10 in middle-aged women).
conclusionDespite interest in vitamin D as a low-cost strategy to prevent or reduce UI, our findings indicate oral vitamin D may not reduce urgency/mixed UI progression.
