ADAG, A_1C derived average glucose;

^aHemoglobin<13 g/dL in men, <12 g/dL in women; T.bil, total bilirubin; Alk-P, alkaline phosphatase; CI, confidence interval.

^* P<0.05.

Multivariate analysis: included all variable with P values <0.05 in the univariate analysis, age≧65 years, male and gas formation.
