Statistical analysis
The statistical package for the social science (SPSS- version25) is used to analyze the data. Socio-demographic variables of participants were assessed using descriptive statistics, including mean, frequency count and percentage for binary and categorical variables. The mean and standard deviation (S.D.) was used for normally distributed continuous variables, while median and interquartile range (IQR) for not normally distributed variables. The chi-square test was used in assessing the presence of any influence study demographics and clinical presentation on mortality and complications of patients. P value <0.05 is considered statistically significant.
