Modeling was based on multiply imputed data sets (n=40) with attained age as time scale. AAA indicates abdominal aortic aneurysm.
a
Reported numbers was based on complete set data and do not add up due to missing data.
b
Additional adjustments for total energy intake (continuously) and with all variables in the table simultaneously included in the model.
c
Estimate of never/former drinkers not interpreted due to the low number of cases in this group (n=5).
