  • DASH, Dietary Approaches to Stop Hypertension.

  • a Adjusted for country (fixed effect in competing risk analysis and random effect in all others), sex, daily physical activity, education (secondary versus none/primary), diabetes, smoking (current or former versus never), myocardial infarction, vascular access type (fistula versus graft/catheter), body mass index (categories according to the World Health Organization), albumin (tertiles), Charlson comorbidity score (quartiles), age, phosphorus, calcium, hemoglobin, Kt/V, and energy intake (1000-kcal/d increase).

  • b All above adjustments plus adjusted for having a life partner, time on dialysis, and being waitlisted for transplantation. Sensitivity analyses excluded the first 12 months of follow-up (786 all-cause deaths of 2087 and 334 cardiovascular deaths of 829 were excluded).
