Furthermore, in the Kaplan–Meier survival curve analysis of cumulative AD mortality by blood Cd quartile at baseline, the highest quartile (Cd concentration 0.6 μg/L) was associated with a borderline significant decrease in survival when compared with the lowest blood Cd concentration quartiles ( p = 0.0684), suggesting the potential role of Cd in AD pathogenesis and as a predictive marker of a poor prognosis of AD [ 144 ].
