  1. Data were adjusted for sex, age, and BMI and are presented as mean ± S.E
  2. a subjects carrying both non-risk alleles of APOA5 and APOE
  3. b subjects carrying both risk alleles of APOA5 and APOE
  4. *P < 0.05. The percent (%) change of each lipid level due to carrying the combination of the risk alleles of APOA5 and APOE was calculated by dividing the mean value of the difference between CC + CG/CC + CT and GG/TT genotypes of APOA5/APOE by the mean value of CC + CG/CC + CT genotype and multiply the answer by 100
