Table 1.

Bland–Altman agreement results between EncephaLog biomarkers and biomarkers from each of the three technologies used (top row—Android, bottom row—iOS) across all trials, including Mean of differences ( $\bar{d}$ ), confidence intervals (95%), and the p value for two tailed t-test comparing the differences to zero. (-) Marks biomarkers that could not be derived from the pressure mat. All confidence intervals include 0, and all p-values > 0.05, indicating that we cannot reject H0, therefore we can state that the biomarkers are similar and there is a fine agreement between EncephaLog and each of the three methods.
