Statistical analysis
Statistica version 13 (StataSoft Inc., Tulsa, OK, USA) was used for analysis. The normality of the data was determined using the Shapiro-Wilk test and histograms. Data that was normally distributed was presented as mean ± standard deviation, or frequency (percentage), while skewed data was presented as median (interquartile range). The differences between baseline and 12-week are presented as effect sizes using Cohen’s d. The differences between study groups were determined using dependent t-tests. Independent t-tests and analysis of covariance (ANCOVA) were used to determine the differences in absolute changes in outcomes of interest between the control group and intervention groups. The dependent t-test was performed to determine mean changes between the intervention and controls. The effect sizes were interpreted as large (≥ 0.8), moderate (0.4 to 0.8), small (0.2 to 0.4), and trivial (< 0.2). Significance was set at
