Assessment of vitamin D levels in patients with alopecia areata: a case-control study in a Tertiary Care Hospital in North India.
Article in Annals of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionAlopecia Areata (AA) is a T-cell-mediated autoimmune disorder. Vitamin D acts as an immunomodulator potentially relevant to pathogenesis. Since data from North India remains limited, this study aimed to assess serum 25-hydroxyvitamin D [25(OH)D] levels in AA patients compared to matched controls and evaluate correlations with disease severity.
methodsThis hospital-based case-control study included 44 AA patients and 44 matched healthy controls. Disease severity was assessed using the Severity of Alopecia Tool (SALT) score. Serum 25(OH)D was measured using Chemiluminescence Immunoassay (CLIA).
resultsMedian serum 25- hydroxyvitamin D was significantly lower in cases (17.10 ng/mL) versus controls (22.60 ng/mL;
conclusionsSerum 25- hydroxyvitamin D deficiency is significantly associated with Alopecia Areata in this North Indian cohort, particularly among urban residents. Screening for deficiency may be a valuable addition to management.
