^*Note: 80 Mean = Treatment – Baseline.

^**Negative values for the effect size indicate decreased values relative to baseline (improvement); positive effect size indicates increased values relative to baseline (worsening).

^***Cohen’s d is positive if active is greater, negative if sham is greater.
