Statistical Analysis
Descriptive statistics (mean (SD), median [interquartile range], and
%(N), as appropriate), were presented for MV complexity scores, patient
demographics, and comorbidities. Kappa values were reported for the
agreement of TEE scores and surgical scores. McNemar’s tests were used
to test the homogeneity of the marginal probabilities of different
scoring categories. All statistical analyses were performed using SAS,
version 9.4.
