Table 1.

Main results. Original MNI coordinates for GM volume findings from Kanai et al., 2010, Kanai et al., 2011 are reported in column 1, rows 1–6. Rows 7–8 reports replication tests based on the van Loon et al. (2013) study. Column 2 reports the condition: The ROI condition uses spherical ROI with a radius of 15 mm centred on the original peak. The exact condition uses the exact original peak coordinate. The Mask condition uses a mask consisting of all significant voxels in Kanai et al. (2010). The large and small conditions use large and small voxels for GABA MRS, both centred on the calcarine sulcus. Bayes factors (BF) are reported in favour of the original hypothesis using uniform one-sided priors and using informative priors based on the number of participants (N) and correlation coefficient (r) reported in the original studies.
