Standard deviations are shown in brackets. Significant differences (p < 0.05) between C and D1 or C and D2 are marked with asterisks and were calculated with a student’s t -test. Significant differences (p < 0.05) over time were calculated separately for C (capital letters), D1 and D2 (small letters) via repeated measurement ANOVA (Tukey-HSD) and are indicated by different letters.
