  1. d = Cohen's effect size, 1-β = power. The sample size required for a statistically significant difference is provided for CPT given the effect size d of the underlying data of CPT and the power 1-β set at 0.8 (Nrequired), and given the effect size d in EPT and the power 1-β set at 0.80 (Nd,1-β) (see [70]).
