Data are expressed as mean ± standard deviation; a Effect size was classified as trivial or no effect (SMD < 0.2), small (SMD = 0.2 to 0.59), moderate (SMD = 0.6 to 1.19), large (SMD = 1.20 to 2.00), very large (SMD = 2.00 to 3.99), and extremely large (SMD > 4.00) according to Hopkins et al. [50]; SMD: standardized mean difference.
