Note: statistical results are presented in the form of the following data: the first line is the median (Me), the second line is the lower and upper quartiles [Quartile 25%; Quartile 75%].

*p < 0.05 – significant intergroup difference. Comparison of 3 independent groups according to the Kruskal-Wallis test; comparison of 2 groups – according to the Mann-Whitney test (^1/2 I and II degrees, ^1/3 I and III degrees; ^2/3 II and III degrees).
