Data are shown as or median (interquartile range). Abbreviations: CHC, combined hormonal contraception containing estrogen plus 2nd- or 3rd-generation progesterone; ΔAbsmax, maximum absorbance at the plateau phase; CLT, clot lysis time; D-Dmax, maximum D-dimer levels in the lysis assay; D-Drate, maximum rate of increase in D-dimer levels in the lysis assay; s, fibrin clot permeability coefficient.
