aData presented as mean (an estimate of population mean based on 5,000 bootstrap samples) ± SD of the sampling distribution (the estimate of the sample SE). The associated two-tailed p-values are obtained as proportion of sampling distribution of absolute differences between 5,000 randomized group means that are at least as extreme as the difference between original groups mean.
bData presented as n (%). The associated p-values are Fisher’s exact two-tailed probabilities.
