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