Fig. 2: Distributions of transformed 25-hydroxyvitamin D (25OHD) and vitamin D binding protein (DBP) by the six diplotypes, within the European ancestry subgroup.

The colors represent the six diplotype combinations. The center lines show the medians; box limits indicate the 25th and 75th percentiles; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles; outliers are represented by dots. The sample sizes for the 1 F/1 F, 1 F/1 S, 1 F/2, 1 S/1 S, 1 S/2 NS 2/2 diplotypes for a 25OHD are 1452, 10,986, 5262, 21,694, 20,644, and 4950 respectively; and b DBP are 1501, 11,077, 5314, 21,883, 20,801, and 5013 respectively.
