  • *Adjusted for age (decades), gender, BMI (>30 kg/m2) and prior diuretics using a forward step-wise binary logistic regression model with gout in the index joint as the dependent variable.

  • NS, not significant; MTP, metatarsophalangeal; DIP, distal interphalangeal; PIP, proximal interphalangeal.
