Effects of clinical and demographic factors on stable warfarin dose by univariate linear regression analysis

Covariate	P value	Trend in univariate linear regression
Heritage	P < 0.049	−2.4 mg/day for AN
Age	P < 0.008	−0.05 mg/day for increase of 1 year in age
Gender	P < 0.30	+0.72 mg/day for men
Statin	P < 0.013	−1.67 mg/day with concurrent statin use

Heritage, age, gender, and statin use were all included in the multivariate regression model to assess genotype‐dose associations.
