  1. Asthma classification according to GINA [75].
  2. A Shapiro-Wilk test showed that FEV1 is normally distributed (p > 0.05) while FVC is not (p = 0.008). Thus, a t-test was used for the analysis of FEV1 while a Mann–Whitney test was used for FVC. Statistically significant p-values were found for comparisons between mild persistent and moderate-severe persistent asthma, denoted in bold.
