Study design. A total of 932 patients were enrolled during January and February 2019. An additional 207 patients from Zhengzhou 2019 and 79 from Shenyang Shengjing hospital were included as the external validation data sets. Patients without sex (n = 11) and prognosis (n = 22) information were excluded. Then, 913 unique patients were randomly divided into two mutually exclusive samples for training (66.7% [609 patients]) and testing (33.3% [304 patients]). All analyses were conducted using SAS® statistical software version 9.4 (https://www.sas.com).
