  1. Model 1: unadjusted; Model 2: adjusted for age, sex, and current smoking (versus non-smokers); Model 3: Model 2 plus adjustment for infrequent exercise (versus frequent exercise), daily alcohol consumption (versus infrequent/no alcohol consumption), BMI, CRP and eGFR. *Current quartiles are identical to those in Table 1. The numbers of subjects in the previous amylase quartiles are 144, 149, 157, and 121 for Q1-Q4, respectively. **The ranges of values for the prior serum amylase quartiles are 30-55, 56-69, 70-85 and 86-198 IU/l for Q1-Q4, respectively.
