RE: Surface-based morphometry data
Thank you so much for your reply,
Regarding question #5 do you know when Dr. Radua will respond to it? Or should I contact them directly through email? If yes, will you please provide this information to me?
I have one other question also:
I am only including whole-brain studies in my meta-analysis. The measure I am interested in is local Gyrification Index (or lGI) computed on FreeSurfer software. All my included studies conduct vertex-wise analyses of lGI: specifically examining lGI differences between groups vertex-by-vertex (or point-by-point) across the entire cortex, and report clusters in which lGI is significantly different between groups (and I report the peak coordinates of these clusters in my meta-analysis).
However, one study (although it is a whole-brain study) conducts ROI-based analyses of lGI. Meaning that: it looks at lGI differences between groups across the entire brain in ROIs (33 gyral regions- based on Desikan atlas) instead of vertex-by-vertex and ultimately gives ROIs in which lGI is significantly different between groups (and I report these peak coordinates in my meta-analysis).
I just want to make sure that the above is okay, or if you recommend that I exclude this study from my meta-analysis?
I'd really appreciate your reply,
Thank you so much,
Avi
