Clinical significance of the neutrophil-lymphocyte ratio as an early predictive marker for adverse outcomes in patients with acute pancreatitis

Table 2 Sequential changes in the neutorphil-lymphocyte ratio in mild acute pancreatitis and severe acute pancreatitis groups

NLR 0, Neutorphil-lymphocyte ratio at admission; neutrophil-lymphocyte ratio (NLR) 1, on day 1; NLR 2, on day 2; NLR 3, on day 3; P value < 0.05. Value expressed as median NLR (IQR). MAP: Mild acute pancreatitis; SAP: Severe acute pancreatitis; IQR: Interquartile range.
