Statistics
All statistical analysis was performed using SPSS Statistics 26 (IBM
Corp., USA) and graphs were constructed using Prism 8 (GraphPad Software
Inc., USA). Continuous variables are expressed as mean ± standard
deviation, and categorical variables are expressed as percentages.
Normality of data samples was assessed using Shapiro-Wilk test. Two
sample hypothesis testing was performed using either Student’st -test if samples had normal distributions or Mann-WhitneyU test if samples did not have normal distributions. Hypothesis
testing for categorical variables was performed using Fisher’s exact
test. For Kaplan-Meier survival analysis, significance testing between
groups was performed using log-rank test.
All patients provided written informed consent for their procedures, and
all data collection and analysis was approved by the NYU Langone Medical
Center Institutional Review Board.
