Statistical Analysis
Continuous variables were represented as median (interquartile range [IQR]) and compared using the Mann-Whitney test (for two way comparisons) or Kruskal-Wallis test (for three way comparisons) as they were not normally distributed by testing with the Kolmogorov-Smirnov test. Categorical variables were represented as proportions and compared using chi-square and Fisher’s exact tests where appropriate. P-value less than 0.05 was considered significant for all analyses. When Kruskal-Wallis test or chi-square tests showed significance, post-hoc comparisons with Bonferroni correction were further performed to examine the significant differences pairwise. Chi-square tests were used to evaluate differences between those with and without stroke. All statistical analyses were performed using IBM SPSS software version 26.0 (IBM, Armonk, NY, USA).
