Direct comparison between IPF (n = 51, red squares) vs. CTD-ILD (n = 25, green dots). IPF area 0–1: Red squares indicate correctly recognized IPF patients. Green dots denote false positive patients. CT-ILD area 0–−1: Green dots represent correctly identified CTD-ILD, while red squares mark false negative results. The dotted line is inserted around the threshold for uncertain cases and included two patients. Abbreviations: IPF-Idiopathic pulmonary fibrosis, CTD-ILD-connective-tissue diseases- associated ILD.
