Pairwise comparison unfolded a significant increase of IL-17A in patients with ICIaP compared to lung cancer (p = 0.011) and to ILD other than ICIaP (0.004) but not to healthy controls (p = 1.000), whereas IFN-γ showed no significance in pairwise comparison with ICIaP. The gene discussed is IFNG; the disease is lung carcinoma.
