  1. Note: *=significantly different from the non-obese group (p<0.05); CI confidence interval. Predicted differences in mean cost by obesity status are based on simple log-linear regressions for all acute-care hospital stays (in constant Canadian dollars). All parameters are bootstrap weighted for population representation averaged over the period of observation
