Data is presented as median (25th; 75th percentile). TG, treated group, n=27; CG, control group, n=27. Diff., p-values; significance of the difference between the groups within each time point or over time within either group. Results of the pairwise comparisons between time points: a, significantly different from the baseline; b, significantly different from 24 hours. NS, not statistically significant; S, statistically significant.
