Table 5 Outcomes on treatment burden. Annual treatment burden of patients choosing dialysis versus patients choosing conservative care, measured from treatment decision (part A). Annual treatment burden of patients started on dialysis—a subgroup of all patients choosing dialysis—measured from start of dialysis (part B)

  1. a= Hospital free days are calculated using the formula: 365.25 – (annual incidence rates of outpatient visits + in-hospital days + in-center haemodialysis days)
  2. b= Adjusted for age, sex, Davies comorbidity score, and estimated glomerular filtration rate
  3. c= Adjusted for age, sex, and Davies comorbidity score
