In the few studies involving plasma biomarkers, for overall patients, a prospective study enrolled 158 Han Chinese patients with ARDS risk factors from the respiratory and emergency intensive care units showed that AUC of LIPS + AngII for predicting occurrence of ARDS was 0.803 (95% CI: 0.727−0.879), sensitivity and specificity were 0.711 and 0.797, respectively [43], LIPS + AngII also exhibits good predictive capability in our population, with an AUC of 0.814 (95% CI: 0.760−0.869), a sensitivity of 0.853, but a decreased specificity of 0.697. This evidence concerns the gene AGT and acute respiratory distress syndrome.
