Magnitude of the reference's group–level z–statistics relative to the raters' distribution.

Side	Stimulation	Mean	±SD
Left	Ipsilateral	0.05	±1.07
Right	Ipsilateral	0.30	±1.35
Left	Contralateral	−0.09	±1.27
Right	Contralateral	0.49	±1.30

The reference group–level z–statistic for each voxel was scaled by the distribution of z–statistics from the other raters. Presented here are the mean and standard deviations of the standardized reference z–statistics. A mean of 0 would indicate that the reference has the same z–statistic as the other raters (on average); values greater than zero indicate greater z–statistics than the raters' average; and values lower than zero indicate lower z–statistics than the raters' average.
