Additional file 1: SMethods. Figure S1. Representative images of each of the characteristic pulmonary opacities on chest computed tomography scans. Figure S2. Distribution of registered patients by years. Figure S3. Cumulative proportion of the duration (h) between chest computed tomography examinations and initiation of veno-venous extracorporeal membrane oxygenation support. Figure S4.
