Serum 25 hydroxyvitamin D was positively associated with hemoglobin and other anemia parameters in children: a cross-sectional study.
Article in Nutrition & metabolism, 2025. 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
backgroundPrevious in vitro studies indicated that 25 hydroxyvitamin D [25(OH)D] might contribute to the modulation of anemia parameters while epidemiological evidences were scarce in children. We explored the associations of 25(OH)D with hemoglobin (Hb) and other anemia parameters (mean corpuscular volume [MCV], mean corpuscular hemoglobin concentration [MCHC], and serum ferritin [SF]) in children.
methodsA cross-sectional study involving 10,227children (mean age 14.6 months) in Nantong, China, was carried out. Serum 25(OH)D, MCV, MCHC, and SF concentrations were measured.
resultsAfter adjustment for the potential covariates, serum 25(OH)D was positively associated with anemia parameters (quartile [Q] 4 vs. Q1: 127.304 vs. 78.982 g/L for Hb; 83.957 vs. 66.264 fL for MCV; 334.551 vs. 208.368 g/L for MCHC; 34.277 vs. 32.807 ng/mL for SF). Similar results were shown in the stratified analyses by gender. Consistently, a higher 25(OH)D was found to be related with a lower risk of anemia (OR
conclusionsIn general, our findings provided further support for the anti-anemia effects of 25(OH)D in Chinese children. Further research is warranted to replicate these results in different populations and in experimental settings.
