Statistical analysis
The proportion of automated points that matched the paired manual points
with respect to local activation times and mesh vertices were
calculated, along with corresponding 95% confidence intervals.
Correlations between matched pairs were assessed by McNemar tests.
Two-tailed P-values <0.05 were considered to indicated
statistical significance. Analyses were performed using SAS software
version 9.4 (SAS Institute, Cary, NC).
