Abstract
Combined oral contraceptives show clear differences in effect on the tissue factor-initiated coagulation test of activated protein C resistance, which is dependent on the presence and dosage of levonorgestrel. Multiphasic lev onorgestrol oral contraceptives differ from monophasic contraceptives and r esemble third-generation contraceptives.
