Increasing CD34+CD133+ EPC quartiles also had a reverse relationship with the risk of all-cause dementia among those who had CHD (P = 0.05, Figure 2D), HTN (P = 1.8 × 10−4, Figure 2F], stroke (P = 0.02, Figure 2H), silent infarct (P = 0.01, Figure 2J), CMB (P = 0.02, Figure 2L), or had a high WMHI level (P = 0.03, Figure 2N]. This evidence concerns the gene CD34 and stroke disorder.
