"Funding This work was supported by JSPS KAKENHI (Grant Number JP22K09120) and the TSUCHIYA MEMORIAL MEDICAL FOUNDATION, a Grant-in-aid for multicenter clinical research from Japanese Association for Acute Medicine, and Japan Agency for Medical Research and Development (AMED, Grant Number JP23fk0108654)."

"Using data from the intensive care units (ICUs) at 24 institutions across Japan, we developed the J-CARVE registry—a retrospective database of patients with severe ARDS on V-V ECMO. Institutions that intended to participate in this registry had to submit a participation form available on the J-CARVE registry website (https://www.ace-registry.net) and needed to have treated at least 10 patients with severe ARDS who required V-V ECMO. The study was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR) before starting data collection (UMIN000048709). The registry was approved by the Institutional Review Board of Hiroshima University Hospital (E-2768), which waived the requirement for obtaining informed patient consent to ensure participant anonymity, as stipulated in the Japanese government guidelines. The details of the J-CARVE registry data collection and quality control are described in Additional file : SMethods."
