1-Castelli’s Risk Index (CRI-I) = TC/HDLc
2-Castelli’s Risk Index (CRI-II) = LDLc/HDLc
3-Atherogenic Coefficient (AC) = (TC– HDLc)/HDLc
4-CHOLIndex = LDL-C − HDL-C (TG <400) = LDL-C – HDL-C + 1/5 TG (TG >400).
AIP >0.1
Castelli Risk Index (CRI-I): TC/HDL>3.5 in males and >3.0 in females,
Castelli Risk Index CRI-II: LDL/HDL >3.3
Atherogenic Coefficient AC: TK-HDL/HDL >3.0,
CHOL Index : LDL-HDL >2.07.
