Amplitude correction factors for various patient groups.

The first column indicates the derivation. The subsequent 8 columns contain the amplitude correction factor of that derivation (averaged over the two five-minute periods) in various patient groups. Grouptype and groupsize are indicated in the first and second row, respectively. Note that in all groups, F4-M1 has the largest amplitudes while Fz-Cz and Fpz-E1 have the smallest and Cz-Oz is closest to the traditional C4-M1 amplitudes.
