Data not available on all 44 patients; number given in brackets.
Chronicity defined as any abnormal of serum ALT, T Bili or Alk Phos 6 months after presentation
Only 36 subjects whose duration can be calculated with observed bilirubin level < 2.5
Only 16 of the patients came for their 6 month follow up
Percentage of chronic patients at 6 months followed up at 12 and 24 months
