Table 3 Comparison of inflammatory markers (peripheral blood eosinophil count (PBE), and FeNO) between adherent participants with and without ongoing sputum eosinophilia. Sample medians and interquartile ranges are presented and compared using Wilcoxon’s test

From: Serum prednisolone levels as a marker of oral corticosteroid adherence in severe asthma

  Adherent participants without ongoing sputum eosinophilia (n = 8) Adherent participants with ongoing sputum eosinophilia (steroid resistant) (n = 6) p-value
PBE (cellsx109/L) 0.02 [0, 0.08] 0.20 [0.2, 0.4] 0.003
FeNO (ppb) 12 [9.5, 15.5] 43 [41, 48] 0.002
