Table 1 gives descriptive statistics for percent power difference (PPD) and absolute value of the PPD (APPD) corresponding to Figure 1 (PPD and APPD defined in methods). The mean APPD was 2.74% showing tight concordance between simulated study power and EEE approximated power. When one considers that the simulated power levels, by being random variables are themselves prone to some error, this degree of concordance is all the more impressive.
