Correlation between log peak shear stress and absolute increase from the proximal artery to the distal artery. (A) Platelet CD62P, (B) percentage of platelet-monocyte aggregates (PM-Agg). PA indicates proximal artery; DA, distal artery. Solid lines shown are derived from linear regression analyses; r and P values shown are derived from correlation analyses. Dotted lines intersect y-axis = 0.
