Figure 4.
Direct comparison between IPF (n = 51, red squares) vs. COP (n = 28, green dots). IPF area 0–1: Red squares indicate correctly-recognized IPF patients. Green dots denote false positive patients. COP area 0–−1: Green dots represent correctly identified COP patients, 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, COP-cryptogenic organizing pneumonia.
