Kaplan–Meier analysis of all-cause mortality rates during a 51-month follow-up of 515 chronic haemodialysis patients. The relative risk of mortality was significantly greater in the group with lower baseline serum magnesium levels (<1.14 mmol/L, n = 261) than in that whith the higher baseline serum magnesium levels (≥1.14 mmol/L; n = 254) [76]. All-cause mortality, P < 0.001 (log-rank test); after adjustment by Cox multivariate analysis, P < 0.05. Reprinted from Ishimura et al. [76], with permission.
