The meta-analysis ALE map summarizes 77 VBM studies published in 58 articles. Gender information was missing in 3 MRI VBM studies. A Fisher exact test was conducted to compare men/women counts, and an unpaired T-test was conducted to compare group mean ages. After Bonferroni correction for two tests, none of the differences observed was significant at level p = 0.05.
