Table 5.

Correlation between West African ancestry and warfarin dose prediction for patients requiring doses ≥60 mg/week.

Algorithm	Pearson r	R²	β^*	P
Novel African American	0.25	0.06	−1.8	0.19

WAA, West African ancestry

SD, standard deviation

Unstandardized

IWPC clinical algorithm was not able to predict doses within 20% of therapeutic doses ≥60 mg/week and therefore excluded.
