CRP and infection: For predicting infection, the accuracy of PEV was significantly higher than that of CRP levels (p = .0002), Ranson scores (p = .0222), Marshall scores (p = .0179), CTSI scores (p = .0036), and EPIC scores (p = .0022), and its accuracy was similar to that of BISAP scores (p = .1057) and APACHE II scores (p = .0955).
