Differences in human group mean SEP between sexes: with reference to the Rohrer's index

With 200 SEPs of normal subjects, the differences in the Group Mean SEP between sexes were defined eliminating the differences attributable to another peripheral factor relating to the nutritional condition represented by the Rohrer's index. The differences in the baseline amplitude of the Group Mean SEP between males vs. females in the section between roughly 23-111 msec, around 330 msec, and behind 389 msec in latency were verified, subtracting the differences between the groups with a high vs. low value of the Rohrer's index, not attributable to the different nutritional condition, and might be the central origin. Applying the Amplitude Scaling, the differences in the section 23-104 msec in latency were verified similarly, being more a significant indication of the sex difference per se.
