NHANES data on Hcy and vitamin deficiencies.
These scatterplots lump together the NHANES studies for 2001–2006. Data is for men and women between ages 20 and 40. The red dotted curves show the mean Hcy concentration of vitamin bins of small size. RBC folate and B6 are in nanomolar, B12 is in picomolar, and plasma Hcy is in micromolar. RBC folate stands for red blood cell folate.
