Treatment effects are shown for the start and end of the study. Seventeen positive differences (shown in bold) indicate improvement over time. Of these, four treatment-time interactions, two for the sham and two for the anodyne treatment, were significant at the 5% level (last two columns). Although the positive differences in effect size are not all statistically significant, 11 of 17 times there was an improvement of the sham treatment, whereas there were only six positive differences for the anodyne treatment.
