CH_LDL−CH_HDL: Concentration difference between LDL and HDL at the inner wall surface in high-speed flow group.
CL_LDL−CL_HDL: Concentration difference between LDL and HDL at the inner wall surface in low-speed flow group.
RH_LDL−RH_HDL: Difference value of ratio of concentration between LDL and HDL at the inner wall surface in high-speed flow to concentration in bulk flow.
RL_LDL−RL_HDL: Difference value of ratio of concentration between LDL and HDL at the inner wall surface in low-speed flow to concentration in bulk flow.
