Fig. 1 Wisconsin and Brasfield chest X-ray scores for F508del/F508del group (n=38) and pancreatic sufficiency group (n=19). The bands show the 95% confidence interval for each group, and the dashed lines indicate the threshold value for probable radiographic irreversibility [20,32]. Group comparisons using GEE models adjusting for center, gender, meconium ileus status, and age revealed that the pancreatic sufficiency group was significantly better than the F508dek/F508del group in WCXR [estimate (p-value), −4.01 (p<.001)] and BCXR [estimate (p-value), 1.46 (p=.001)] scores. From ages 7 and 8 years, there were significant differences in WCXR and BCXR scores, respectively, between groups by t test comparisons, i.e., at each age interval.

Fig. 2 The % predicted FEV1 and % predicted FEF25–75 for F508del/F508del group (n=38) and pancreatic sufficiency group (n=19). The bands show the 95% confidence interval for each group. Group comparisons using GEE models adjusting for center, gender, meconium ileus status, and age revealed that the pancreatic sufficiency group was similar to the F508del/F508del group in % predicted FEV1 [estimate (p-value), 5.45 (p=.12)] and % predicted FEF25–75 [estimate (p-value), 8.26 (p=.27)]. There were no significant differences in % predicted FEV1 and % predicted FEF25–75 between groups for any ages by t test comparisons.

Fig. 3 Comparison of patients 1 and 2 with novel CFTR mutations with the F508del/F508del and pancreatic sufficiency groups on the longitudinal WCXR scores. The segments show the 95% patient-wise lower prediction interval (calculated as described under Statistical analyses) and the dashed line at WCXR=5 indicates the threshold for probable radiographic irreversibility [20,32].

Fig. 4 Categorization of “mild” mutation patients with the F508del/F508del and pancreatic sufficiency groups based on the longitudinal WCXR scores. The segments show the 95% patient-wise lower prediction interval (calculated as described under Statistical analyses) and the dashed line at WCXR=5 indicates the threshold for probable radiographic irreversibility [20,32].
