aHypothesized region of interest activations were derived from an 8 mm sphere around activation center and hypothalamic areas from a 4 mm sphere.
bESs = standard deviations calculated as follows: differences between negative versus neutral signal intensity changes in men versus EF women and men versus LF/MC women; differences are divided by the SD of signal intensity value of the whole sample.
cThe differences between two different signal intensity values (i.e. men vs EF women and men vs LF/MC women) was tested formally using PROC MIXED in SAS. This procedure fits mixed linear models and handles repeated measurements in order to take into account the variance of the two different measurements (EF and LF/MC) for each woman in the current study.
