The crude odds ratios were significantly lower than 1.0 for the group with the highest calcium level (0.94; 95% CI, 0.89 to 0.99), but when adjusted for magnesium levels there was no difference between the groups with different levels of calcium. 39. traitement chelateur. diagram of the endocrine feedback control of humoral disorders Magnesium 5, 150-153.

This study used a death certificate-based case-control study and a drinking water quality ecology study to examine the relationship between hypertension mortality and calcium and magnesium exposure from drinking water in Taiwan. mechanisms of Mg homeostasis which also control the metabolisms Methods—All eligible cerebrovascular deaths (17 133 cases) of Taiwan residents from 1989 through 1993 were compared with deaths from other causes (17 133 controls), and the levels of calcium and magnesium in drinking water of these residents were determined.
