“…In this study, twelve variables including age, ALT, total bilirubin, CK-Mb, PT, WBC, amylase, total calcium, creatinine, HCT, lactate, and lipase which were identified to be significant difference by univariate analysis were set as the input layers, and the most important four variables including total bilirubin, amylase, ALT and creatine were identified, which also were reported in other studies. Evidence showed that the levels of total bilirubin and ALT were significantly higher in AP patients with a Ranson score ≥3 [ 23 ], and early elevated creatinine within 24 hours after admission was a good predictor of fatal outcomes in AP patients [ 24 ]. Serum level of amylase was not only for AP diagnosis but also associated with severity and prognosis of AP [ 25 , 26 ].…”
