Figure 4. Change of individual volumetric measures of MCI subjects as diagnosed at baseline over two years. Error bars are standard errors. Mixed-model repeated-measures analyses were used to assess between-group differences (group × time interaction) in changes from baseline to 24 months. Only the measures that were significantly different between MCI stable and MCI-to-AD converters were tested (as labeled in Table 4) and only the measures with a significant group × time interaction in the subsequent analyses are shown here.
