Agreement between clinicopathological diagnosis and histological diagnosis by the simplified criteria for autoimmune hepatitis and other liver diseases

Clinicopathological diagnosis	n	Histological category by the simplified criteria*
		Typical AIH (%)	Compatible AIH (%)	Atypical AIH (%)
AIH	38	3 (5.1)	33 (55.9)	2 (3.4)
AIH-PBC overlap syndrome	10	1 (1.7)	7 (11.9)	2 (3.4)
PBC	2	0 (0.0)	0 (0.0)	2 (3.4)
NASH	6	0 (0.0)	0 (0.0)	6 (10.2)
Cryptogenic	3	0 (0.0)	1 (1.7)	2 (3.4)

Data presented as number and percentage.

The agreement between clinicopathological diagnosis and histological diagnosis by the simplified criteria was shown in the grey boxes.

*The simplified scoring system for AIH condenses liver histology criteria into three categories: ‘typical' when in addition to interface hepatitis, rosetting and emperipolesis are present, ‘compatible' when not all three features are present, and ‘atypical' when there is evidence of an alternative diagnosis.

AIH, autoimmune hepatitis; AIH-PBC, autoimmune hepatitis overlap with primary biliary cholangitis; NASH, non-alcoholic steatohepatitis; PBC, primary biliary cholangitis.
