Flowchart of case inclusion in the study. Of the 465 patients with institutional diagnosis of IIPs in the nationwide cloud-based integrated database, 21 were diagnosed as having ILD other than IIPs by web-based MDD and were excluded. Because of insufficient data on HRCT findings, nine patients were excluded. Of the 435 patients with web-based MDD diagnosis of IIPs, 16 were diagnosed as having idiopathic PPFE and were excluded. Consequently, 419 patients with MDD diagnosis of IIPs except for iPPFE were enrolled in this study.
