When considering patients with sepsis, only the L/A ratio and C-reactive protein levels demonstrated low diagnostic accuracy for predicting the need for mechanical ventilation (L/A ratio, AUC = 0.894, cut-off point = 0.344, (0.696, 0.185); C-reactive protein, AUC = 0.738, cut-off = 15.950, (0.652, 0.325)) and the L/A ratio exhibited low diagnostic accuracy for predicting mortality (AUC = 0.707, cut-off point = 0.338, (0.520, 0.175)), while C-reactive protein had a low diagnostic accuracy with AUC = 0.638 (cut-off point = 15.45 (0.540, 0.318)) (see Fig. 5a and b). Here, CRP is linked to Sepsis.
