Mean fasting blood glucose, hematocrit, hemoglobin, and lipid levels in each of the genetic classifications.

SD: Standard deviation. A: One-way analysis of variance (ANOVA), significance p<0.05. K–W: Kruskal–Wallis test, significance p<0.05.
Glc: Glucose. Ht: Hematocrit. Hb: Hemoglobin. T-Chol: Total cholesterol. HDL-C: High density lipoprotein-cholesterol. LDL-C: Low density lipoprotein-cholesterol. K+: K allele carriers. K−: K allele non-carriers. R+: R allele carriers. R−: R allele non-carriers. K+/R+: K and R allele carriers. K+/R−: K allele only carriers. R+/K−: R allele only carriers.
