Figure 2: Adjusted risk of death following initiation of dialysis among patients aged 65–74 years at the time of starting dialysis (based on 9076 of 9096 patients who had complete data). Point estimates show the estimated hazard ratio associated with each variable; the 95% confidence interval (CI) around the estimate is shown as a horizontal bar. The variable “era effect” is the hazard ratio for death between patients who began dialysis in era 2 (1995–1999) and those who began it in era 1 (1990–1994). Vascular disease is defined as the presence of either peripheral vascular disease or cerebrovascular disease, or both, at the time of dialysis initiation.
