Figure 1: Showing Validated COMBI scoring system
The principal author gathered data and made phone contact. Verbal
consent was obtained, and responses were documented in an Excel
spreadsheet.
Statistical analysis :
Data was assessed for normality of data distribution with Shapiro Wilk
test. 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.
