Data presented as Mean ± SD or Median, (IQR). Bold denotes significant p-value. For continuous variables, between group differences were compared using the Student t-test for parametric data and the 2-sample Wilcoxon rank sum test for non-parametric data. Proportions were compared using the Fisher Exact Test.
