SEPSIS, ARDS
For the present study, mean ± standard deviation (Mean ± SD) and median and quartiles [M (Q1, Q3)] were adopted to described the normally-distributed and nonnormally-distributed of measurement data, respectively. The differences of the groups were compared by the t-test and Mann–Whitney U test. And the categorical data were presented by the number of cases and the constituent ratio [N (%)], and the χWe conducted a difference analysis between the training set and testing set. In the training set (n = 11,566), patients with sepsis were divided into ARDS group (n = 2422) and non-ARDS group (n = 9144) according to whether ARDS occurred, and we also did a difference analysis between the ARDS group and non-ARDS group. Lastly, we developed and validated the predicting performance of developed model by ROC and calibration curves. The relative risk (RR) and 95% confidence interval (CI) were calculated. In addition, we deleted the variables with more than 20% missing values (ALT, ALB, TG, LDL-C, HDL-C, AST, NEUT, SaO
