Association of the APOA4 variant (rs5110, Q360H, lipid increasing allele=C) with the year 3 plasma dp-ucMGP (natural log-transformed) in men and women. Note: Based on a paired t-test, the change in total MGP from baseline to 3 year was not significantly different for any genotype in women (all p > 0.15). Total MGP declined in men for both genotypes (p=0.04). In men and women, for genotype A/A, n=0.
