Demographics of ADNI data with means and standard deviations of age, global CDR, and MMSE in each group. There were no statistical differences of age and gender between the three groups with 𝑃>0.05. The MMSE latest score for MCI converters was chosen as the measure right after conversion and for MCI stables and controls was selected as the latest measure in the database.
