Figure 2

Kaplan–Meier estimates of the rate of conversion from mild cognitive impairment (MCI) to Alzheimer's disease (AD) for rs7840202, rs11637611 or rs12752888. Panels showed the effect of genotypes (CC is the minor homozygous genotype group vs non-CC groups) on the rate of conversion from MCI to AD diagnosis in APOE ɛ4 carriers (+) and non-carriers (−). The Cox proportional hazards model was used.
