Figure 1.

Direct comparison between idiopathic pulmonary fibrosis (n = 51, red squares) and HC (n = 33, green dots) by Aeonose^®. IPF area 0–1: Red squares indicate correctly recognized IPF patients. Green dots denote false positive patients. HC area 0–−1: Green dots represent correctly identified healthy controls, and red squares mark false negative results. The dotted line is inserted for values around the threshold where there is doubt about which side it tends to, and, hence, reflects an area of uncertainty. Abbreviations: IPF-Idiopathic pulmonary fibrosis, HC- healthy controls.
