Drug levels at time point of genotyping were quantified using HPLC/MS/MS as described in the method section. In addition, two internal controls (Control_1; Control_2) were used as references. Bold values indicate too low concentration of the indicated drug (<C min). DRV 1*800 indicates a dosing scheme of 800 mg darunavir once-daily, DRV2*600 refers to the dosing of 600 mg twice-daily. The C min and C max values are obtained from the patient information leaflets provided by the manufacturer. Regardless of the mode of ingestion, values for darunavir were available for twice-daily (DRV 2*600) only. All values are given in ng/ml
