Circannual prevalence of vitamin D insufficiency in older and minoritized ethnic adults in Northern Britain: screening outcomes from a clinical trial.
Trial report in European journal of clinical nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
backgroundVitamin D is essential for bone and metabolic health. Deficiency remains a global health issue, particularly among older adults and ethnic minorities with darker skin pigmentation. Data on circannual variation these groups remain sparse. SUBJECTS/
methodsThis study reports vitamin D status in older adults ( ≥ 65 years) and ethnic adults ( ≥ 18 years, Fitzpatrick classes IV-VI) in northern Britain, assessed during the screening phase of a supplementation trial. Participants were screened for inclusion between December 2024 and August 2025. Serum 25-hydroxyvitamin D (25(OH)D) was assessed in dried blood spots followed by LC-MS/MS analysis.
resultsIn total, 299 participants were screened. Vitamin D insufficiency or deficiency ( < 50 nmol/L) was noted in 54.8% of older adults and 72.1% of ethnic individuals. These rates did not decline during summer months.
conclusionThese findings highlight persistently high rates of vitamin D insufficiency across high-risk groups in northern Britain and underscore the inadequacy of sunlight exposure as a corrective measure.
