AP, acute pancreatitis; ANA, antinuclear antibodies; +, increased antibody or presence of infiltrate; −, absence of increased antibody or infiltrate.
Score grading: 0 or 1, probably not autoimmune chronic pancreatitis (ACP); 2, possible ACP; 3, probable ACP.
Cluster grading: 1, probably not ACP; 2, probable ACP.
