Statistical analysis
The number of energy applications required to successfully puncture the
septal tissue for each treatment condition was assessed as a mean with
standard deviation (95% confidence interval). The paired t- test
was used to compare the number of applications. Levene’s
test was used to assess the homogeneity of variances. A probability
value of <0.05 was used to determine statistical significance.
Analyses were performed using Excel software (Microsoft Office 10,
Microsoft, Seattle, USA).
