Frequency of Serum ARV Levels Below Cmin for the EI-AED Group Compared to the NEI-AED Group

ARV levels below Cmin (analysis based on all AED/ARV overlap intervals) EI-AED Group n (%) NEI-AED Group n (%) P-value
 None 10 (62.5) 23 (76.7) 0.124
 One level below Cmin 4 (25) 7 (23.3)
 Two levels below Cmin 2 (12.5) 0 (0)
ARV levels below Cmin (analysis after exclusion of intervals with EI-AED levels below reference range)
 None 4 (40) 23 (76.7) 0.008
 One Level below Cmin 4 (40) 7 (23.3)
 Two Levels below Cmin 2 (20) 0 (0)

ARV, antiretroviral drug; Cmin, minimum recommended serum concentration; EI-AED, enzyme-inducing antiepileptic drug; n, number of AED/ARV overlaps; NEI-AED, non enzyme-inducing antiepileptic drug
