Data are expressed as the mean± standard error. t: The t-test statistic for a paired sample t-test; p: The p-value (probability value) for the t-test statistic. * was considered significant at p < 0.05; ** was considered significant at p < 0.01; *** was considered significant at p < 0.001 for paired-sample t-test. The effect size is reported by Cohen’s d.
