Logistic regression models assuming additive associations of country income level, age at onset, and 12-month comorbidity with severe role impairment fit the data better (Akaike information criterion=434.1; Bayesian information criterion=468.1) than models that also included all two-way interactions (Akaike information criterion=438.0; Bayesian information criterion=531.6) or all two-way and three-way interactions (Akaike information criterion=458.1; Bayesian information criterion=561.3).
