AGT and acute respiratory distress syndrome: Although AngII showed the difference between ARDS and non-ARDS in baseline parameters, but it was excluded by Cox proportional hazard regression analysis, which might be because it played a greater role between ARDS and non-ARDS (p=0.018), who admitted to SICU due to extrapulmonary factors, shown in Table S1(b), but our study built a model based on overall patients.
