Binary logistic regression analysis indicated that NRBC count (OR = 204.434, p < 0.05), PCT (OR = 1.076, p < 0.05) and CRP level (OR = 1.011, p < 0.05) were independent predictors of poor prognosis in AP patients, and higher levels of the indicators suggested poorer prognosis (Table 4). This evidence concerns the gene CRP and alkaline phosphatase measurement.
