Results of multiple regression analysis with neuropsychological test results.

<p>Results of multiple regression analysis of all 55 participants (13 MCI converters, 14 MCI non-converters, 28 healthy controls) adding neuropsychological test results (MMSE, Clox 1, verbal memory, visual memory, Trail A) as covariates. Worse neuropsychological test results for the variables MMSE and verbal memory were positively correlated with higher gray matter atrophy of the left Putamen/Sub-lobar (coordinates <i>x</i> = −14, <i>y</i> = 8, <i>z</i> = −11, <i>k</i> = 1163, <i>T</i> = 4.26, <i>Z</i> = 3.91, <i>p uncorr</i>. = 0.000) (left) and the left inferior frontal gyrus (right) (coordinates <i>x</i> = −39, <i>y</i> = 23, <i>z</i> = −2, <i>k</i> = 206, <i>T</i> = 4.19, <i>Z</i> = 3.85, <i>p uncorr</i>. = 0.000).
