2.8. Statistical Analysis
After extracting the required data from the patients’ records, the data
were analyzed using SPSS, version 18. In addition, descriptive data for
continuous variables and qualitative statistics were reported as bar
charts and tables. The mean difference test (independent t-test) was
used to compare the patients. Moreover, Chi-square was utilized
comparing both groups of studies for qualitative variables. P value less
than of 0.05 was considered significant.
