The tests of interactions between HDL-c, LDL-c and apoB/AI ratio appeared non-significant results (In stroke group, HDL-c p for interaction=0.246, LDL-c p for interaction=0.517; In non-stroke group, HDL-c p for interaction=0.774, LDL-c p for interaction=0.211). This evidence concerns the gene APOB and stroke disorder.
