Panel A depicts the association between the levels of F1.2 and PS-positive red blood cells. Panel B presents correlation between F1.2 and PS-positive platelets. The open and closed circles represent data points from patients with the SC and SS genotypes, respectively. The solid lines represent the linear-regression fit to the data, and the dotted lines represent the 99% confidence interval curves.
