The magnitudes of the ORs for the SES variables were attenuated when compared to the bivariate results, but each SES variable remained statistically significant for radiographic, bilateral radiographic, and symptomatic knee OA (association of non-managerial occupation and bilateral radiographic knee OA was of borderline significance, OR = 1.24, 95% CI 0.99, 1.55, P = 0.056).
