Hello,

I made an analysis thanks to the QDEC tool : I tested a correlation between an inhibition score and cortical thickness, corrected for age (continuous = inhibition score ; nuisance = age ; smoothing = 25 and FDR corrected)

*** ***** ** *********** * *********** ******* *** ********** ***** *** ******** ********* ** ***** ****** ************** *****

then, I realised a ROI analysis. I extracted different statistic values from this orbito-frontal region following your wiki (aparcstat2table). Thus, I obtained for each participant, the average value of medial orbitofrontal cortical thickness. Finally, I made a multiple linear regression analysis on R software which is a statistical software. Surprisingly, « R », indicated that it doesn't exist any correlation between the right medialorbito frontal thickness values and the inhibition scores. I don't understand why. Can you help shed some light on this issue ?

Yours sincerely

Marine Moyon
