Note: Results include sample sizes (n), difference of means (Mean Diff), standard deviations for the difference of means (Std Dev), t‐test statistics (T), and p‐values (Sig), and BH adjusted p‐values (BH Adj).

Note: Bold p‐values indicate significance at 0.05 and BH values below critical value α = 0.05.
