What was measured

The 4-item AES was used to ensure there were no baseline group differences in expectations related to the benefits of acupuncture on dry mouth and to assess aspects of blinding after the first 4 weeks of acupuncture for the TA and SA groups. The AES is reliable (α=0·82) and valid by positive correlation with patient self-reported efficacy and satisfaction. The scale has been further validated among cancer patients who were acupuncture naïve. Scale from 4-20.

Analysis population: Intent to treat analysis excluding standard oral hygiene group. Considered and utilized all data available at each timepoint. AES was not collected for the standard oral hygiene arm per protocol specifications. Standard oral hygiene participants were not to receive any form of acupuncture making this outcome not applicable for these participants and therefore not collected.
