Note.
Age was covaried in all analyses. Tabled significance (P) values are based on treatment-group-by-linear-trend interaction results in GEE analyses, reflecting the effect over the total 7-year time period. Adjusted means (in brackets) are adjusted for age and for the baseline value of the outcome variable at the follow-up time point. Effect sizes are shown only for those specific time points that were significant, and were calculated on difference scores from baseline.
