Note: Values shown are means (±SE). Examining across rows, for the same variable, values with different superscripts differ significantly from one another, using Bonferroni correction (p<0.008). Thus, the mean 6-month PCS score of 46.0±0.6 was significantly different from the baseline score of 43.6±0.5, as shown by the different superscripts (b vs. a). Baseline and 6-month values for MCS were not significantly different, as shown by the shared superscript a.
