Fig. 6. Some of the significant correlations (nc=34, nv=34, all bars p<0.05) between linear combinations of lipoproteins in carotid plaques and plaque pathology reports are shown in the white bars. The lipoproteins were determined by extraction, ultracentrifugation, and denaturing gel electrophoresis. The variation shown in the black bars is calculated from principal component analysis of sample lanes in gel images.
