Data are means ± SD. * Friedman Repeated Measures Analysis of Variance on Ranks (Dunn's post hoc test) for comparisons in the control and HAD groups (basal vs. all months). ^# Mann-Whitney U-Rank Sum test for comparisons in basal and every month concentrations between the control and HAD groups. P < 0.05 in all cases.
