Results from sub-group analysis based on chi-square test analysis. a. Subjects stratified by vitamin D deficiency at 25(OH)D < 20 ng/mL. b. CF mutation types categorized by F508del homozygous, F508del heterozygous, or no F508del mutation c. Pancreatic enzyme usage, yes or no, recorded at the start of study d. Subjects stratified by whether they were diagnosed with CFRD e. Subjects stratified by vitamin D insufficiency at 25(OH)D < 30 ng/mL. An asterisk (*) indicates statistical significance at p < 0.05.
