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.
