For group distributions, the mean and standard deviation (SD) are reported for normally-distributed data, while the median is reported with lower and upper distribution quartiles [Q1, Q3] for non-normal data. For group comparisons, the mean difference and bootstrapped standard error (SE) are reported, along with the bootstrap ratio (BSR) and percentile-based p-value.
