aStratified by study. Mutually adjusted for the other two beverage types.

bStratified by study and adjusted for smoking (never, former, ≤10 cig/day, 11–19 cig/day, ≥20 cig/day); education (primary, unfinished secondary, secondary, higher); BMI. Mutually adjusted for the other two beverage types. Age was used as the underlying time metric for all analyses.

cTest for trend was carried out across three categories by fitting ordinal variable ‘amount per one occasion’ as continuous.

dResults for MIHDPS and KRIS participants are presented separately due to differences in questionnaire design.
