Data analysis was carried out using Prism Version 5 software. Normality of data were tested using the Shapiro-
Wilk test, with all data being found to be normally distributed. Baseline characteristics data were compared
between groups using independent t-tests. All other data were analyzed using a two-way (group and time)
repeated-measures ANOVA with bonferroni corrected post hoc t-tests, where appropriate. When a time effect
was noted a one-way ANOVA was carried out for each group, with bonferroni correct post hoc t-tests comparing
each time point with baseline where appropriate. Statistical significance was accepted at p < .05. Data are
presented as mean ฑ SD.
