Poor Correlation of Rivaroxaban Concentration with the Routine Coagulation Screening Test in Chinese Patients with Atrial Fibrillation

Figure 1

Mean and 95% confidence intervals (CI) of routine coagulation tests obtained for different arbitrary classes of rivaroxaban trough concentrations (Ctrough). The normal range of prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), and thrombin time (TT) were 9–13 s, 0.8–1.2, 20–40 s, and 14–24 s, respectively. The dotted lines represent the upper limit of the normal range: (a) PT, (b) INR, (c) aPTT, and (d) TT.
