Correlation between urinary albumin excretion rate and expression of platelet surface markers, active GPIIb/IIIa, and P-selectin. Correlation between urinary albumin excretion rate and expression of platelet surface markers, active GPIIb/IIIa, and P-selectin. The patients were divided into two subgroups based on aspirin intake: for active GPIIb/IIIa, those not taking aspirin (A) (γ = 0.60; P < 0.001) and those taking aspirin (B) (γ = 0.51; P < 0.001), and for P-selectin, those not taking aspirin (C) (γ = 0.57; P < 0.001) and those taking aspirin (D) (γ = 0.34; P < 0.001). Log-transformed values were plotted on each figure. Shin-ichi Araki et al. Dia Care 2009;32:2062-2067 ©2009 by American Diabetes Association
