Participants from Norway and Sweden are all non-consumers of decaffeinated coffee and were excluded. dIncludes 299,890 participants. Participants from Norway were excluded as their information on tea intake is not available. eCut-off points are based on country specific quartiles of beverage intake after exclusion of non-consumers; low: quartile 1, high: quartile 4. fCut-off points are based on country specific tertiles of decaffeinated coffee intake after exclusion of non-consumers; low: tertile 1, high: tertile 3. gIn first degree relative (available for 43% of women). hOnly for parous women. iUsing Cambridge Physical Activity Index. jFor caffeinated coffee categories, median decaffeinated coffee intake is given and vice versa.
