In the intervention group, 9/15 participants (60%) had total suppression, 4/15 (26.6%) had partial suppression, and 2/15 (13.3%) had no suppression. In the control group, 2/15 participants (13.3%) had partial suppression and 13/15 (86.6%) had no suppression.
In the intervention group, mean (±SD) VAS scores were 9.1 (±0.6) points at T0, 2.0 (±2.7) points at T1, and 6.7 (±1.6) points at T2 (Figure 1A). The mean reduction in VAS scores between T0 and T1 was 7.1 (±3.1) points. This reduction was statistically significant (Wilcoxon signed-rank, z = 3.40, p = 0.0006). The mean reduction in VAS scores between T0 and T2 was 2.4 (±1.8) points. This reduction was statistically significant (Wilcoxon signed-rank, z=2.93, p = 0.0034). Seven participants in the intervention group achieved VAS of 0 points at the T1 timepoint.
