Rise in Serum 25-Hydroxyvitamin D Levels during the COVID-19 Pandemic.
Article in Nutrients, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
With the emergence of the COVID-19 pandemic, the absence of established evidence-based treatment protocols led healthcare professionals and the public to explore experimental treatments, including high doses of vitamin D supplements. This study aimed to assess changes in serum 25-hydroxyvitamin D levels during the pandemic, employing a retrospective cohort analysis of data from Charleston Area Medical Center (CAMC). The study analyzed serum 25-hydroxyvitamin D levels in a cohort of 35,556 patients treated at CAMC in 2019, a representative pre-pandemic period, to 2021, a representative pandemic period. Our findings revealed a significant increase in mean serum 25-hydroxyvitamin D levels as compared with 2019 (37 ± 21 vs. 31 ± 15 ng/mL,
