Statistical Analysis
Unpaired two-sided t-tests and Fisher’s Exact tests were performed for
continuous and categorical variables, respectively. Survivorship between
patients undergoing FEES was compared to the control group using the
Kaplan-Meier method and the log-rank test. Patients were censored at
date of death or most recent follow-up as appropriate. All statistical
analyses were performed using R Software (version 3.6.3; R Core Team,
Vienna, Austria) with a defined α = 0.05.23
