Coefficients of genetic and environmental factors in the general linear model for HDL-cholesterol levels.

a)Adjusted for age (continuous), sex, and regions (site1 to site6).
b)Adjusted for age (continuous); sex; regions (site1 to site6); smoking; drinking; daily activity (metabolic equivalents: METs); habitual exercise (METs); intake of egg, meat, and fish; BMI; and SNPs except ABCA1 rs2422493.
c)P-values less than 0.0038 were considered nominally significant for 13 SNPs after applied Bonferroni correction.
d)Score variables (1–3) were used according to number of reference alleles.
e)Adjusted for age (continuous); sex; regions (site1 to site6); smoking; drinking; daily activity (METs); habitual exercise (METs); intake of egg, meat, and fish; BMI; and SNPs except ABCA1 rs1800976.
