Sex-specific quintiles (Q1-Q5) in the overall cohort
Categories of tea intake were defined as: non-consumers (C1); and the sex-specific quartiles among tea consumers (C2-C5) in the overall cohort.
Stratified for age at recruitment (in 1-year intervals) and for centre. Adjusted for sex. Norway was not included in analyses concerning tea intake as this information was not available.
Stratified for age at recruitment (in 1-year intervals) and for centre. Adjusted for sex, diabetes mellitus (self reported at enrolment), education, body mass index, smoking, physical activity, alcohol intake, categorically as in Table 2 and energy intake (ordered in quintiles). Norway was not included in analyses concerning tea intake as this information was not available.
As model 2 but simultaneously including tea and coffee intake. Norway was not included in analyses concerning tea intake as this information was not available.
