Relative Risk (95% Confidence Interval) of Plaque Progression Associated with the Highest Quartile of Small Dense LDL Cholesterol Compared with the Lowest Quartile in Subgroups of Known Cardiovascular Risk Factors

CI, confidence interval; LDL, low-density lipoprotein; LDLC, low-density lipoprotein cholesterol; RR, relative risk; sdLDL, small dense low-density lipoprotein.

Relative risk was calculated using a modified Poisson regression model after adjustment for known cardiovascular disease risk factors, lipid-lowering treatment, large buoyant LDL cholesterol. ^†P value for interaction analysis.
