p values are for group differences assessed by one-way analysis of variance (ANOVA). For a given outcome measure, when ANOVA showed statistically significant findings (p < 0.05), all pairwise comparisons among groups were tested for statistical significance using the least significant difference test. The pairwise comparison that was significantly different is indicated in the following footnote.
∗ CON vs HE, p = 0.022.
# LE vs HE, p = 0.043.
@ CON vs LE, p =0.015.
& CON vs HE, p =0.049.
