Figure 1From: A combined genome-wide linkage and association approach to find susceptibility loci for platelet function phenotypes in European American and African American families with coronary artery disease Summary of the factors derived from the Principal Components Analysis (PCA) in European Americans and African Americans on 37 phenotypes measured pre-aspirin (A), post aspirin (B) and post-adjusted-for-pre aspirin (C). Each column represents a single factor and the color block indicates a phenotype with PCA loading > 0.4 for the specific factor. (* = where applicable).Back to article page
