Statistical analysis
Statistical analyses were performed with SPSS version 25. The two groups were compared for statistical significance based on Chi Square or Fisher exact test for categorical variables which are expressed as percentages. All continuous variables were explored for normality using normality diagnostics. Student’s t-test was used to analyze continuous variables that were normally distributed, and the Mann-Whitney U test was used for variables that had non-normal distributions. Continuous variables were expressed as means ± standard deviations and/or median with 25th and 75th percentile as appropriate. Statistical significance was based on a two-tailed P value of less than 0.05. Details for the repeated measures analysis and linear regression are provided in the Supplement.
