Maternal concentrations of vitamin D metabolites in response to high-dose oral vitamin D during first trimester pregnancy: a randomized controlled trial.
Article in BMC nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Vitamin D deficiency has become a common problem globally. The present study aimed to evaluate the effects of different vitamin D3 regimens on maternal concentrations of vitamin D metabolites during pregnancy. Subjects were ≤ 14 weeks gestation pregnant women with 25(OH)D serum level < 30 ng/mL]. Two intervention groups were randomly assigned: 5,000 IU of vitamin D3 daily or 50,000 IU weekly of vitamin D3. Maternal blood samples were collected before and after four weeks of intervention to assess changes in serum concentrations of 25-hydroxyvitamin D (25(OH)D), 1,25-dihydroxyvitamin D (1,25(OH)
