a Interaction between Lipoprotein lipase gene SNP rs1121923 and fat energy intake (%) on HDL-C concentrations (Pinteraction = 0.003). Among those who consumed a high fat diet, T allele carriers had significantly higher levels of HDL-C compared to the CC homozygotes (P = 0.0002). b Interaction between Lipoprotein lipase gene SNP rs1121923 and fat energy intake (%) on HDL-C as a categorical variable (Pinteraction = 0.01). Among those who consumed a high fat diet (28.4%), the individuals who carried the T allele have 30% reduced risk of low HDL-C levels compared to those who carry the CC genotype (P = 0.001). Data shown are represented as means ± SE. Pinteraction values adjusted for age, gender, body mass index, type 2 diabetes and total energy intake
