Prevalence of Low Serum Vitamin D Levels in Patients Presenting With Androgenetic Alopecia: A Review.
Review in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled it.
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
The role of vitamin D receptor (VDR) has been well established and extensively studied in the hair cycle. Its deficiency is also closely linked to several types of alopecia, including alopecia areata, telogen effluvium, and androgenetic alopecia (AGA). Since there is limited research on the correlation between androgenetic alopecia and low serum vitamin D levels, our review aims to find relevant articles and comprehensively present them. A review of the literature was performed to gain insight into AGA. Specifically, PubMed and Google Scholar databases were searched to identify any relevant articles with a focus on androgenetic alopecia, male pattern baldness, and serum vitamin D levels. References within the included articles were also reviewed and taken into the study if found appropriate. All articles that met the inclusion criteria were analyzed for demographics, clinical, laboratory, radiographic, treatment, and outcomes data. We found 13 relevant studies that elucidated the relationship between low serum vitamin D levels and androgenetic alopecia and included them in the review. We concluded that serum vitamin D might be a possible parameter for diagnosing the onset and severity of AGA. Vitamin D supplementation has proven to be useful in the regrowth of hair in non-human subjects. Vitamin D could be a valid therapeutic approach, such as topical vitamin D (calcipotriol) seems to be a good treatment option to regrow hair follicles and prevent miniaturization of follicles due to androgenetic alopecia.
