  • Correlation (Pearson correlation coefficient, r) between ICM chloride secretory responses and sweat chloride concentration is given, as displayed in figure 2A-D and described in the results.

  • Diagnostic patients were classified into CF unlikely and PS-CF diagnostic according to ICM and extensive CFTR genotype analysis; the CF group includes all subgroups (PS-CF diagnostic, PS-CF known and PI-CF known) together.

  • CF, cystic fibrosis; ICM, intestinal current measurement; Isc, short-circuit current; PI, pancreatic-insufficient; PS, pancreatic-sufficient.
