Table 3. Slopes of the regression lines used to determine group sVEP thresholds.

The slopes differ for contrast (CS) and vernier offset (VA) sweeps but not for grating / spatial frequency (GA) sweeps. The number of infants (n) in the calculation of each mean is shown below each entry in the table. IVH, intraventricular hemorrhage.
