Initial dosing should be prioritized to optimize INR stability; confirms limited role of anticoagulant half-life or education intensity beyond variability.
Does the half-life of oral anticoagulants or the intensity of patient education improve the stability of anticoagulation levels in patients starting therapy?
Neither the half-life of the oral anticoagulant nor the intensity of patient education significantly affected overall INR stability, suggesting that initial dose determination is the most critical factor.
