Note: Values shown are mean (± SE) changes from baseline, as assessed at month 2, 6, and 12. P values show the comparison between the Surgery and Lifestyle Groups at each time point. Bolded values represent statistical significance at the p≤0.016 level (to account for comparisons at multiple time points). Increases on the Short Form-36 subscales represent improved functioning.
