*P values based on Kruskal–Wallis test or chi-square (normal distributed or categorical variables, respectively) for the comparison of the three groups, lung cancer (LC), chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). HP- Hypersensitivity pneumonitis; NS—Non-significant (p value > 0.05); NA—Not applicable. a—results based in pairwise Welch's t-tests.
