There was a marginally significant relationship between body-mass index and the post-dose plasma nevirapine concentration at week 2 (Pearson’s r = -0.31, p = 0.051), but not at week 4 (r = 0.02, p = 0.90) or week 8 (r = 0.09, p = 0.64), and no significant relationship between body-mass index and pre-dose nevirapine concentrations at week 2 (r = -0.013, p = 0.92), week 4 (r = -0.06, p = 0.69) or week 8 (r = 0.20, p = 0.25) (Fig. 2 ).
