  1. OR, odds ratio.
  2. For both models, age and year of first gout consultation are fitted linearly. aAdjustment made only for matching variables (age, year of first gout consultation, gender, practice). bAdjustment made for matching variables and potentially confounding factors (type II diabetes mellitus, ischaemic heart disease, hypertension and diuretic prescription).
