There were no differences between treatments at 12 months. Data are mean ± SD for normally distributed and geometric means (95% CIs) for non–normally distributed data; for the latter, P values from the log-transformed data are presented.
P < 0.05 12 months vs. baseline;
P < 0.05 15 months vs. baseline;
P < 0.05 15 months vs. 12 months.
