- 1 values are mean ± SD
- a p values are group x time of assessment interaction and were obtained by repeated measures ANOVA analysis
- Experimental group, MNP and NMS; Control group, NMS only
- Difference between groups at same time point is significant (at the 0.05 level) when letters are same
- * Significantly different by paired t-test between baseline and selected time-point in the same intervention group at the 0.05 level
- ** Significantly different by paired t-test between baseline and selected time-point in the same intervention group at the 0.001 level
- 2 p value after adjusting for sex (Model 1) at 12 months, groups were compared using one-way ANCOVA
