SAMPLE SIZE CALCULATION
In this study, GPOWER statistical software (v. 3.1, Franz Faul, Universität Kiel,
Kiel, Germany) was used to evaluate the sample size, assuming a mean difference
and standard deviation (SD) of 0.55, type 1 error (α) of 0.05, and type 2 error
(β) of 0.1 to achieve a statistical power of 90%
