Serum Vitamin D Levels and Risk of Iron Deficiency Anemia in Adults: A Cross-Sectional Study and Mendelian Randomization Analysis.
Review in Food science & nutrition, 2025. 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
This study focuses on the potential role of vitamin D in the diagnosis and treatment of iron deficiency anemia (IDA), and evaluates causation using Mendelian randomization (MR). This cross-sectional study collected clinical information from 3728 respondents in the National Health and Nutrition Examination Survey (NHANES) cycles of 2005-2010 and 2015-2018. To determine the link between serum vitamin D levels and the risk of IDA, we established a robust nomogram. Calibration and net clinical benefits were examined through calibration curves and decision curve analysis (DCA). Restricted cubic spline (RCS) models were utilized to explore the relationship between the two. In addition, the data of single nucleotide polymorphism (SNP) related to vitamin D and IDA were obtained from open biological databases. The main analytical method for the MR analysis was the inverse variance weighted (IVW) method. A series of sensitivity analyses were conducted to evaluate pleiotropy. Our cross-sectional study showed that, after extensive adjustments, serum vitamin D levels remained an independent risk factor for predicting the development of IDA. The risk of developing IDA was significantly lower for participants in the highest quartile subgroup with vitamin D levels ≥ 78.1 nmol/L compared to those in the lowest quartile with vitamin D levels ≤ 42.8 nmol/L (
