^aEffect size is defined as the absolute value (difference from baseline to follow-up measure) divided by the SD at baseline.

^bP-value from Wilcoxon-signed ranked test comparing the time period to baseline.

^cP-value from Wilcoxon-signed ranked test comparing the time period to previous time period.
