  1. Note: Data were shown as mean ± S.D. *P<0.05, compared with the Control group; #P<0.05 compared with Sham AA group. (For Chi-Square tests among three groups, the adjusted significance level for each comparison was set at P = 0.017(0.05/3) to give a significance level of 0.05 over all three tests: *P<0.017, compared with the Control group; #P<0.017 compared with Sham AA group). AA: auricular acupressure; T1: the time-point on the morning of one day before trans-vaginal oocyte retrieval; T2: the time-point on the morning of the day of embryo transfer; STAI: state trait anxiety inventory; APAIS: Amsterdam preoperative anxiety and information scale.
