As depicted in Table 2, LUS (odds ratio [OR] = 6.699, 95% confidence interval [CI] [2.607, 17.216], p < 0.001), EVLWI (OR = 6.080, 95% CI [2.512, 14.718], p < 0.001), and UCA1 (OR = 5.078, 95% CI [2.094, 12.315], p < 0.001) were independent indicators for forecasting the outcome of patients with ALI. Here, UCA1 is linked to acute respiratory distress syndrome.
