* Note that at each time point adding the change from baseline scores to the post treatment scores will not necessarily equal the baseline scores, because some patients have dropped out after the baseline

SD = Standard Deviation

NS = Not significant

# the table has some missing data on VAS scores at baseline, but data available on other outcomes. One participant in the massage group and 3 in control group did not complete VAS pain scores, and thus were not included in the later comparisons to baseline.
