CRP and acute respiratory distress syndrome: Obvious differences between ARDS and non-ARDS groups were discovered in MBP (P < 0.001), respiratory rate (P = 0.002), temperature (P = 0.004), PaO2 (P < 0.0 01), Lac (P < 0.001), PCT (P < 0.001), PaO2/FiO2 (P < 0.001), CRP (P < 0.001), qSOFA score (P < 0.001), SOFA score (P < 0.001) and CURB-65 score (P < 0.001) (Table 1).
