Serum Vitamin D Levels and Risk of Iron Deficiency Anemia in Adults: A Cross-Sectional Study and Mendelian Randomization Analysis.

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.
