The increase in platelet tissue factor expression 3.5 hr after UFP exposure (relative to baseline) approached significance [see Supplemental Material, Figure 2A (doi:10.1289/ehp.1002237)] ( p = 0.07) and correlated strongly with the previously mentioned significant increases, at this time point, in expression of platelet CD40L ( r = 0.91, p < 0.001).
