AA auricular acupressure, AE adverse events
^aone of the three true AA group participants who dropped out of the preliminary RCT completed the five-day AA and provided via telephone her five-day AA daily log recordings that she completed at home, while the other two participants completed only a two-day AA and log recordings and a three-day AA and log recordings, respectively;
^bcausality between AA and the reported AE was determined using the WHO-UMC System for Standardized Case Causality Assessment
