Table 1. Regression analysis for sexual dimorphism.

A multivariable regression analysis was performed on periorbital thresholds controlling for sex, sham versus SD, single versus repeated SD, and time between SD and allodynia testing. The overall model was significant (F 9.244, p<0.001). Any SD exposure and recurrent SDs were significantly associated with lower periorbital mechanical thresholds. Time between the last SD and allodynia testing was associated with recovery from periorbital allodynia. After accounting for these relationships, there was no association between sex and periorbital mechanical thresholds.
