between the two groups were analysed using Pearson’s correlation
coefficient, and the point where the factor had
relevance to state anxiety score was identified.
After we determined whether the state anxiety scores
were distributed normally, we analysed the data using twofactor
repeated measure analysis of variance (ANOVA); we
set the state anxiety score as the dependent variable, the
within-subject factors as the timing of measurement (on
arrival at hospital and in the room), and the betweensubject
factors as the intergroup comparison (aromatherapy
versus control). When an interaction effect was detected,
we employed the test of simple main effects to detect any
significant differences. Statistical analyses were performed
using SPSS version 21.0 software (SPSS, Tokyo, Japan). A p
