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.
