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).
