Note: p < 0.05 is significant. The reference category for the outcome is unknown HIV status. Reference categories for the independent variables are those not in parentheses. Final Model Fitting Chi-square = 784.97, p = 0.000; Pearson χ2 (212, N = 20,848) = 494.431, p < .05; Deviance χ2 (212, N = 20,848) = 440.596, p < 0.05; Cox and Snell = 0.037; Nagelkerke pseudo R2 = 0.049; McFadden = 0.027.
