  2. a Abdominal symptoms: including abdominal discomfort, abdominal pain, nausea, vomiting
  3. b Abdominal signs: including abdominal tenderness, abdominal lump, hepatomegaly
  4. c Due to poor medical records, blood total bilirubin levels are used to represent jaundice, which < 17.1 umol/L, 17.1 ~ 34 umol/L and >  = 34 umol/L indicates normal, occult jaundice and gross jaundice, respectively
