Data analysisSPSS (version 14) was used for the data analysis. Descriptivestatistics were used to describe the sample characteristics.A Kolmogorov—Smirnov test (K—S test) was conducted toassess normal distributed data. The independent sample t-test and chi-square or Fisher’s exact tests, were calculatedto determine any significant difference in the demographicdistributions. In the three groups, analysis of co-variance(ANCOVA) and Kruskal—Wallis were used for parametric andnon-parametric data respectively. Paired and independentsample t-tests were used to find differences within andbetween the two intervention groups.
