  1. Note. When conducting pairwise t-tests independent variables (IVs), in this case ERH groups, are compared in a pairwise manner, where each group is compared once with each of the rest, using the t-test. As a result, A represents one of the ERH groups and B represents another. Results remained consistent for all DVs. The group of hour 38 had the smallest sample size of 128, so its results may not be as reliable as other groups of ERHs but statistically sound and acceptable, nonetheless.
