Table 3.
Means (standard deviations) of CAPE-V parameters and CPP values at baseline (pre) and after stimulability testing (post) in the total cohort and in groups separated by whether CPP increased or decreased post-stimulability testing.
| Parameter | Total Cohort (n = 27) |
CPP Increase Group (n = 15) |
CPP Decrease Group (n = 12) |
