Figure 2 The comparison of baseline laboratory examinations between rapidly progressive interstitial lung disease (RP-ILD) and non-RP-ILD patients. The values represented standardized values ranging from 0 to 1 by the min-max normalization. * P<0.05 and ** P<0.001. (Created by RStudio software, version 4.2.0.).
