Indicates puff profiles evaluated for evaporative mass loss.
MMAD, mass median aerodynamic diameter; SD, standard deviation; GSD, geometric SD; TB, trachea-bronchial region.
MMAD, if not connected by the same letter (A or B), are significantly different at p < 0.05. Resistance (Ohm: Ω) of the reference e-liquid containing Blankz! pod: Average ± SD (1.87Ω ± 0.02 Ω) with relative SD 1.30%.
