Among the randomized participants, 7 (10.4%) did not com- plete the study. In the experimental group, 29 of 34 patients (85.3%) completed the study while 5 withdrew early, and in the control group, 31 of 33 patients (93.9%) completed the study while 2 withdrew from it. The demographics and characteristics of study subjects are shown in Table 1. There were no statistically significant differences in demographics and characteristics between the two groups (P > 0.05). Table 2 represents the comparison of HRV parameters in the 4th and 12th weeks of treatment in the experimental group. In the 4th week, there were significant differences in mean HR, SDNN, RMSSD, and HF before and after aromatherapy in the experimental group (P
