  1. The difference in gout risk in the overall sugar-sweetened beverage (SSB) category is the average difference from sugar-sweetened beverage category 1 to category 2 to category 3 (i.e. 0, to >0 to <2, to ≥2). All analysis adjusted by age, sex, fruit intake (continuous variable), kidney disease, hypertension, triglycerides, and ethnicity (New Zealand (NZ) Caucasian, East Polynesian, West Polynesian and Mixed East/West Polynesian)
  2. *Analysis adjusted by BMI
  3. **Compared with referent group (0 SSB/day)
  4. P difference between BMI groups =5.9 × 10−4
  5. †† P difference between BMI groups = 0.028
