Fig. 4From: CSF complement 3 and factor H are staging biomarkers in Alzheimer’s diseaseLongitudinal cognitive profiles of subjects in the test set according to initial clinical diagnosis and XMITTN-derived re-classification. P(AD) is the probability of subjects having mild dementia. MCI patients with P(AD) ≥ 50 % have greater executive dysfunction than MCI patients with P(AD) < 50 % (*p = 0.001) and a trend of greater memory dysfunction (p = 0.078). Mild AD patients with P(AD) ≥ 50 % have greater rates of decline in executive functions than mild AD patients with P(AD) < 50 % (**p = 0.007)Back to article page
