Figure 2

Figure 2. Bar graph demonstrates the proportion of activators and deactivators among the four diagnostic groups.. From: Prognostic Value of Posteromedial Cortex Deactivation in Mild Cognitive Impairment.

The proportion of deactivators was significantly different (p<0.05) across diagnostic groups after adjusting for age, education and baseline MMSE score, with significantly fewer deactivators with increasing cognitive impairment grouping.

Figure 3. Bar graph demonstrates activation magnitude parameter estimate in the PMC region (taken from Figure 1), demonstrating a continuum from control, to MCI-Nonconverter, to MCI-Converter, to AD.. From: Prognostic Value of Posteromedial Cortex Deactivation in Mild Cognitive Impairment.

There were statistically significant (p<0.05) differences between all groups with the exception of the control and MCI-Nonconverter group, and the AD and MCI-Converter group. Note the overall pattern of negative activation magnitude in the Control and MCI-Nonconverter groups, and positive activation magnitude in the AD and MCI-Converter groups.
