  4. *Because of missing values, the total number of subjects in each urate quartile is:
  5. For CIMT and men: 1st quartile N = 111, 2nd quartile N = 115, 3rd quartile N = 106, and 4th quartile N = 104
  6. For CIMT and women: 1st quartile N = 117, 2nd quartile N = 123, 3rd quartile N = 120, and 4th quartile N = 115
  7. For plaque score and men: 1st quartile N = 124, 2nd quartile N = 133, 3rd quartile N = 125, and 4th quartile N = 125
  8. For plaque score and women: 1st quartile N = 131, 2nd quartile N = 128, 3rd quartile N = 134, and 4th quartile N = 133
