Multiple regression model predicting log-transformed post-test testosterone concentrations in the female condition. (For the full model: F_3,73 = 31.83, p < 0.001. CAG repeat number and baseline cortisol jointly accounted for 10% of the residual variance in post-test testosterone that was not explained by baseline testosterone. Predictor variables were uncorrelated with each other)

predictor variables	standardized β	ΔR2

log baseline testosterone	0.73
step 2		0.05*
CAG repeat number	−0.15
log baseline cortisol	−0.15
