Continuous variables were reported as mean and standard deviation whereas, categorical variables were reported as frequencies and percentages. Independent sample t-test was used to compare means between the two groups, whereas chi-square test was used to compare categorical variables. Type I error of <0.05 was taken as significant. All individual COMBI questions were compared between the two groups. The responses to each question were reported with mean and standard deviation.
