A New Approach towards Minimizing the Risk of Misdosing Warfarin Initiation Doses

Table 3

Comparing the performance of the revised values of IDP with the original values of IDP, the Gage CL model, and the linear model without IDP. The percentage change in the table represents the percentage decrease in RMSE after revising the IDP.

Threshold	RMSE of the revised IDP	RMSE of the Original IDP; (percent change)	RMSE of the Gage model; (percent change)	RMSE of the linear model without involving IDP; (percent change)
0.1	1.65	2.391 (31%)	2.063 (20%)	2.661 (38%)
0.15	1.76	2.378 (26%)	2.047 (14%)	2.667 (34%)
0.2	1.77	2.392 (26%)	2.051 (13.7%)	2.682 (34%)
0.25	1.9	2.375 (20%)	2.05 (7.3%)	2.68 (29.1%)
0.3	1.96	2.39 (18%)	2.05 (4.4%)	2.681 (26.9%)
0.35	1.96	2.39 (18%)	2.05 (4.4%)	2.681 (26.9%)
