NRGN and dementia: When comparing the magnitude of this effect to the effect obtained from the model contrasting aMCI due to AD against AD dementia (AUC = 0.58, η2 = 0.02, Cohen’s d = 0.29), Ng levels seem to be a more pronounced marker of FTLD dementia over MCI due to FTLD than of AD dementia over aMCI due to AD.
