  • Results are shown as mean (99% confidence intervals).

  • p Values are for test of differences in means between those with and without gout for unadjusted and adjusted analyses.

  • *Multivariable model adjusted for the following variables: age, employment status, marital status, gender, race, education level, current smoking status, medical comorbidity and arthritis comorbidity (other than gout).
