“…Additionally, in four studies (Bozzali et al, 2006;Hämäläinen et al, 2007;Rami et al, 2009;Shiino et al, 2006) the same HCs were contrasted against MCI and AD, respectively; here they were entered into both meta-analyses HC>MCI and HC>AD, respectively. However, study-specific biases are unlikely due to the number of included experiments (see Figure 1) (Heckner et al, 2021;Turkeltaub et al, 2012). MRI scanners included field strengths from 1.0 to 3.0 Tesla, for one study the field strength was unknown, and all incorporated studies performed a VBM whole brain analysis (Ashburner and Friston, 2000;Mechelli et al, 2005), typically with SPM, MedX or FSL.…”
