- aThe predictive accuracy of the models evaluated by Hosmer and Lemeshow goodness-of-fit test was non-significant with P-value > 0.05 suggesting that the model predicted accurately on average. The discriminatory power of the multiple logistic regression analysis as measured by the area under the ROC curve was 0.791. Stepwise modelling was adjusted for univariate variables with P-value < 0.05
