Statistical Analysis
Data were assessed for normality using the Anderson-Darling test.
Continuous, normally distributed data were compared using a two-sample T
test. Categorical data were compared using Chi Square tables. Binary
logistic regression was used to create receiver operator curves and for
multivariate analysis. Spearman’s rank correlation was used to create a
correlation matrix. Minitab version 21 (State College, PA) was employed
for statistical analysis. Alpha <0.05 was considered
statistically significant.
