Fig. 1.

Clinical presentations of autoimmune hepatitis (AIH). Blue bars, green bars, and red bars correspond to East Asia, Southeast Asia, and South Asia, respectively. For reference, additional data reported from some non-Asian countries are also shown as yellow bars. There were no obvious interregional differences in the rates of acute presentation at AIH onset (a) or in the remission rates with corticosteroid-based immunosuppressive therapy (b). c Reports from South Asian countries show markedly high rates of cirrhotic patients at diagnosis (India and Pakistan). Notably, the frequencies of both acute presentation and cirrhosis are low in Japanese AIH patients at diagnosis (see the Clinical Presentation heading in the Epidemiology section).
