Definition of abbreviations: Maximal FEV1 CF%: CF specific percentile for the maximum forced expiratory volume in one second in the last year of data for the subject.
a: P-value reported from chi-squared, assumes equal variance in group means.
b: P-value reported from Kruskal-Wallis test due to unequal variances in group means.
