Statistical analysis
Continuous variables are presented as mean ± standard deviation and
categorical variables as numbers and percentage. The independent
Student’s t-test was used to compare continuous variables. Categorical
variables were analyzed using the χ2test. The
sensitivity, specificity, negative predictive value, and positive
predictive value of echocardiographic diagnosis of CM were calculated
using the results of pathohistological examination as the gold standard.
Accuracy was determined as the sum of true negative and positive tests
divided by all tests. All statistical analyzes were performed using SPSS
version 26.0 software. Values of p<0.05 were considered
statistically significant.
