^*P values at each time point are based on the LSMEAN group comparison analyses from the Mixed Model procedure.

Acup = Acupuncture; XQ = Xerostomia Questionnaire; MDASI = MD Anderson Symptom Inventory; SYM = Symptom subscale; INT = Interference subscale; HN=Head and Neck subscale; UWSFR = unstimulated whole salivary flow rates; SSFR = stimulated salivary flow rates
