2.3. Statistical analysis:
The quantitative variable/s was summarized through descriptive statistic mean and standard deviation (SD), and Inter-Quartile Range. The categorical variable/s was summarized through frequency (%). Comparison of continuous and categorical variables was performed using unpaired t test and chi square test respectively. Strength of correlation between continuous variables like EAT-T by echocardiography and EAT-V by was assessed by Pearson’s correlation coefficient. Univariate regression analysis and multivariate logistic regression analysis was done with EAT-T and indexed EAT-T as predictors to assess association with CAD. Cut-off value of EAT-T for diagnosis of CAD was assessed using receiver operating characteristic (ROC) curve analysis and area under the curve (AUC) by Youden index. P<0.05 indicated statistical significance.
