Low-density lipoprotein (LDL) cholesterol-lowering therapy decreases C-reactive protein (CRP) levels, but the importance of LDL cholesterol-independent effects is uncertain because of the variability in measuring LDL cholesterol and CRP levels in any individual patient. In this study, this variability was reduced by comparing average changes in LDL cholesterol and CRP levels after treatment with lipid-lowering therapy across different studies.
