Log-linear Relationship Between LDL-C Levels and Log-linear Relationship Between LDL-C Levels and Relative Risk for CHDRelative Risk for CHD

• This relationship is consistent with a large body of epidemiological data and with data available from clinical trials of LDL-lowering therapy

• These data suggest that for every 30-mg/dL change in LDL-C, the relative risk for CHD is changed in proportion by about 30%. The relative risk is set at 1.0 for LDL-C 40 mg/dL.
