a Scatterplot of predicted versus actual maintenance dosage. The solid line indicates the line of equivalence, while the dashed line represents the linear fit between algorithm-predicted and actual maintenance warfarin dosages. The plot includes only patients who have achieved stable international normalized ratio (INR), which is defined as attaining therapeutic INR (≥ 1.9 and ≤ 3.1) for two consecutive measurements that are at least 7 days apart. b Bland–Altman assessment of pharmacogenetic dosing model’s predictive performance. Shaded area indicates 95% confidence limits
