a Positive B indicates that men are associated with a higher value for the sensory test (dependent variable) and negative B indicates that women are associated with a lower value for the sensory test (dependent variable).
b Positive B indicates that a higher predictor value is associated with a higher value for the sensory test (dependent variable) and negative B indicates that a higher predictor value is associated with a lower value for the sensory test (dependent variable).
c R2 indicates the proportion of variance in the sensory test (dependent variable) explained by the predicator variable (independent variable).
* Statistically significant at P < 0.05.
