Detailed presentation of CYP2C9 genotype, enzyme activity, metabolism type, and the possible effect on drug concentrations.

Number of patients (%)	Genotypes	Enzyme activity;	Metabolism type	Possible effect on drug concentration
n = 44 (81.48%)	∗1/∗1;	Fully functional;	Normal metabolizers	Drug concentration will remain in the therapeutic range.
n = 10 (18.51%)	∗1/∗2;∗1/∗3;	Decreased;	Intermediate metabolizers	Drug concentration will exceed therapeutic range.

CYP2C9 = Cytochrome P450 2C9 enzyme.
