χ2 or Fisher’s exact test was used for categorical variables depending upon the size of data for each respective variable (i.e., if any one cell in a 2 × 2 table was less than 5, Fisher’s Exact test was used). Student’s t-test or Wilcoxon Rank Sum was used for continuous variables depending upon the normalcy of distribution
