Figure 2. Performance of Dosing Algorithms by Stable Dose Range.

This figure shows the algorithm performance (mean error in mg/week) divided by EHR recorded race and the stable dose range, e.g. patient’s stable warfarin dose is a low weekly dose (<21mg/week), medium weekly dose (21–49mg/week), or high weekly dose (>49mg/week). Mean errors greater than 0 indicate over dosing, while mean errors less than 0 indicate underdosing.
