Statistical analysis
The statistical software SPSS version 23 and Microsoft Office Excel 2010 were utilized to perform statistical analysis. Categorical variables were represented as percentages and counts. To determine if quantitative variables exhibited normal distribution, the Kolmogorov-Smirnov test was used. Numeric variables with a normal distribution were expressed as mean and standard deviation, while those without were expressed as median and inter-quartile range. These measures indicate central tendency and dispersion, respectively. The study employed thorough statistical analysis using three tests: (1) Chi-square test to determine the association between categorical variables, but only when expected counts were greater than 5 in 20% of cells or more, (2) Independent sample t-test to compare means between two groups if numeric variables were normally distributed, or Mann-Whitney U test if non-normally distributed, and (3) Paired t-test to compare means before and after treatment. The data was meticulously analyzed using these tests, displaying a rigorous approach to the study.
