CRP and cystic fibrosis: In 65 participants (age median 19 years IQR [12−26]; CF n = 23, PCD n = 22, controls n = 20) at the University Children ́s Hospital Bochum, we measured taste (salty, sweet, sour, bitter) at four concentrations (“Taste‐Strips,” score 0−16, hypogeusia age‐adjusted < 8/< 9/< 9.9/< 10 points) and smell (“U‐Sniff”‐test, score 0−12, reduced odor identification performance < 8 points), pilocarpine iontophoresis, spirometry, inflammatory markers (e.g., CRP) and subjective chemosensory impairment.
