a For continuous variables, values are medians (IQR); for categorical variables, values are percentages (all such values). P value reflects whether the values of the variables significantly differ between extreme erythrocyte FA/FA-ratio tertiles (Wilcoxon’s test for continuous variables and χ2 test for categorical variables).
