Predicted Nicotine Dependence Syndrome Scale (NDSS) score by CYP2A6 diplotype predicted rate (CDPR) and time calculated using estimates from the linear growth-curve model predicting NDSS (Supplementary Table S-3, NDSS). Solid line with circle represents Slow CDPR, long-dashed line with diamond represents Intermediate CDPR and short-dashed line with triangle represents Normal CDPR. Predicted NDSS score was calculated with controls held at their mean value.
