  1. aMLE to ACM/day was calculated from MLE to nicotine/day using the relationship between ACM and nicotine, determined from calibration smoking (see section 2.4.2).
  2. bFor IS1.0(T), MLE to nicotine per day was calculated by multiplying the average daily consumption e-liquid (mL) per day by the concentration of nicotine (mg/mL) in the cartridge.
  3. cDifferent letters within a group indicate statistically significant differences (p < 0.05) between mean values.
