Plasma anti-Xa activity versus loading time. The plasma anti-Xa activity of (a) rivaroxaban, (b) apixaban, and (c) edoxaban using a rivaroxaban calibrator and (d) apixaban using an apixaban calibrator is shown. The dosage regimens are indicated by black and white dots. The estimated formula with an exponential approximation and the coefficient of determination (R2) is shown.
