  1. Continuous data are analysed with two-tail Student's t-test or Mann–Whitney test, as appropriate (D'Agostino & Pearson normality test). Continuous variables are expressed as medians with 25th to 75th interquartile range (IQR). Categorical variables were examined using Fisher’s exact test. P significant if <0.05 (bold).
