Table shows mean ± standard deviation. Statistical significance: * p < 0.05; *** p < 0.001. Significance was established using a two-tailed Student’s t-test (normally distributed data), Welch’s test (normally distributed data with unequal variances) or the Mann–Whitney test (for pairwise comparisons with at least one non-normally distributed dataset).
