Table 6:
Estimated odds ratios and 95% confidence intervals from three different logistic regression models fit using adjusted survey weights. In each model 5-year mortality is the outcome. The order of variables is presented in order of their inclusion based on the forward selection AUC criteria, and models are nested in order from left to right. The 7 variable model corresponds to the first 7 variables identified by the forward selection procedure. Similarly, the AIC model and AUC model contain the variables selected using the AIC and AUC stopping criteria, respectively. Variables which are derived from accelerometry are highlighted in gray. The intercept for each model is not presented here as variables are not centered and the resulting value is not particularly interpretable.
