Crude and adjusted logistic regression analysis of SUA (per 100 µmol/L) and psychiatric disorders in overall sample.

MDD = major depressive disorder; GAD = generalized anxiety disorder; and SUA = serum uric acid.If P value for the quadratic term (SUA2) is significant, ORs derived from models with quadratic term are presented.Adjusted for age, sex, socio-economic status, alcohol consumption, smoking, diabetes, hypertension, GFR (calculated according to Modification in Diet in Renal Disease equation) and drugs that influence uric acid and additionally for anxiety (in the association between SUA and depression) and depression (in the association between SUA and anxiety).Pinteraction = P value for multiplicative interaction parameter between SUA and sex; Interaction for models with a quadratic term was assessed using a likelihood ratio test (LRT) comparing a model which included SUA*sex and SUA2* sex and a model without; and §indicates P value of the LRT.*Logistic regression not possible due to zero prevalence; NA = not available.
