Linear regression plots for the number of adherent SS RBC/100 μm2 according to the venular diameter in control and PAF-treated preparations.
The adhesion of SS RBC shows strong inverse correlation with the venular diameter (control/SS: r = −.80, P< .00001; PAF/SS: r = −.86, P < .00001). Both intercepts and slopes of the regression lines show significant differences and show that PAF causes a significantly greater adhesion of SS RBC in small-diameter venules, the sites of frequent blockage (SS control intercept 0.41 ± 0.04 [mean ± SE], PAF/SS intercept 1.05 ± 0.08, P < .0001).
