  1. aindicates that Welch’s test was used after the distributions were found to not be of the same shape
  2. Median values are provided if the Mann-Whitney U test was used for comparison; otherwise, mean values are provided. Brackets indicate 95% confidence intervals (CIs) obtained from the estimated PDFs
