The Association Between Polycystic Ovary Syndrome and Vitamin D Deficiency in Infertile Women: A Case-Control Study.

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
Background and Aims: Vitamin D deficiency is a common nutritional problem in women of childbearing age. Polycystic ovary syndrome (PCOS) is a frequent endocrine disorder associated with various metabolic complications. While meta-analyses of interventional trials have explored the role of vitamin D in PCOS, there is a lack of local data from specific populations. This study aimed to provide updated provincial epidemiological data by comparing vitamin D levels in women with and without PCOS, with a specific focus on elucidating the association after adjustment for key confounders, particularly body mass index (BMI). Methods: This retrospective cohort study included 66 women with PCOS and 66 healthy controls. compared vitamin D levels between infertile women with polycystic ovary syndrome (PCOS) and healthy controls. We employed both crude and multivariable logistic regression analyses, adjusting for body mass index (BMI), age, socioeconomic status, and season, to calculate odds ratios (ORs) for vitamin D deficiency. Results: The groups were comparable in age, education, and employment status ( Conclusions: After controlling for major confounders, a significant association between PCOS and vitamin D deficiency persists in this population. This adjusted analysis strengthens the finding that PCOS is an independent correlate of vitamin D status, beyond the effect of BMI. These results support the need for screening and inform future interventional studies.
