Statistics
Because of the small sample size and discrete nature of several outcomes, the descriptive statistics are presented as medians and quartiles. For within-person changes in ordinal or continuous data, the Wilcoxon signed ranks test was used, and for dichotomous data, the McNemar test was used. Since confidence intervals based on medians could be inappropriate, especially since the sample size was small, means of changes are presented with 95% confidence intervals calculated using the paired samples t-test. All reported A priori power calculations were not performed due to lack of information on this intervention for this population. The power calculations for a future RCT were based on the results from the present study using G*Power version 3.1.9.4 with a statistical power of 0.80 and alpha of 0.05 (independent samples t-test; two-tailed).In the between-group analyses of ordinal or continuous data, the Mann–Whitney U test was used, and for nominal data, Fisher’s exact test was used.Analyses were performed using IBM SPSS Statistics version 22.
