AoCaS, aortic calcification score; BMI, body mass index; LDL-C low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; CRP, C-reactive protein.
Values for all variables except age were adjusted for ‘age’ and ‘race/ethnicity’: value of age was fixed at 45.3 years and race was fixed as ‘US White’.
Continuous normally distributed variables were expressed as mean (standard error).
Continuous non-normally distributed variables were expressed as median (inter-quartile range);
Categorical variables were expressed as numbers (%).
p-trend shows p-values for linear and quadratic trend across the alcohol consumption categories.
SI conversion factors: To convert LDL-C and HDL-C to mmol/L, multiply values by 0.0259. To convert triglycerides to mmol/L, multiply values by 0.01129. To convert fibrinogen to μmol/L, multiply values by 0.0294. To convert CRP to nmol/L, multiply values by 9.524.
