  1. Time (p < 0.0001), smoking phenotype classification (p = 0.004), and sex (p < 0.0001) all had a significant effect on V̇O2 max changes over the time (Repeated measures ANOVA). In the model, no significant effect was produced by the product used (EC or HTP, p = 0.144).
  2. ΔV̇O2 max: Absolute change in V̇O2 max with respect to baseline.
