Correlation between wall area percent and spirometry. Values of wall area percent from four airways were averaged and assessed for their correlations with spirometry. Highly significant inverse correlations were identified between wall area percent and MMF. Pearson coefficients for correlations of 6th wall area percent with FEV1 and MMF were − 0.24 (P = 0.0028) and − 0.27 (P = 0.0008), respectively. Pearson coefficients for correlations of 9th wall area percent with FEV1 and MMF were − 0.06 (P = 0.47) and − 0.24 (P = 0.0028), respectively. FEV1 = forced expiratory volume in 1 s; MMF = maximal mid-expiratory flow
