  1. P-value (#1) displayed differences between groups 1 and 2, p-value (#2) between groups 2 and 3 and p-value (#3) between groups 1 and 3. ANOVA and post-hoc analysis according to Hochberg’s GT2 were used and level of significance set at p < 0.05, significant values were marked in bold. SD = standard deviation
