a and b Association between quality of sweat test (proposed criteria) and sweat chloride/sodium ratio. Correct: N = 5,023; mean = 0.784 ± 0.234; median = 0.766; range from 0.06 to 2.51; Incorrect: N = 669; mean = 1.102 ± 0.184; median = 1.071; range from 0.66 to 2.31. p < 0.001. c and d Association between quality of the sweat test and the subject’s age at the time of the examination. Correct: N = 4912; mean = 10.545 ± 16.523; median = 4; range from 0 to 85.58; Incorrect: N = 634; mean = 24.370 ± 22.366; median = 15.92; range 0 to 80.83. p < 0.001. Statistical analysis was performed by Mann-Whitney test. α = 0.05
