However, we did not find the interactive effects between CD34+CD133+ EPCs or the other cell types and the combined vascular diseases for the risk of AD dementia (Table S3), probably due to that the proportion of those without any vascular diseases was small (n = 256) with only 3 cases of AD onset so that we did not have power to detect the interactive effects. The gene discussed is CD34; the disease is Alzheimer disease.
