Predicted incidence rates of death, disaggregated by age (a), RAASi usage (b), time from index (c) and eGFR (d). a light grey line: 60 years, dark grey line: 70 years, black line: 80 years. b grey line: not prescribed, black line: prescribed. c light grey line: 1 year, dark grey line: 5 years, black line: 10 years. d light grey line: 15 mL/min/1.73m2, dark grey line: 30 mL/min/1.73m2, black line: 60 mL/min/1.73m2. The four most important variables for each event (according to the absolute value of the t statistic) were varied, with all other baseline covariates reflective of the cohort average: female; aged 72 years; non-smoker; no history of comorbidities; no medications prescribed; 1066 days elapsed since initial CKD event; no history of heart failure during follow-up period; eGFR 51 mL/min/1.73m2; BMI 29 kg/m2; haemoglobin 13.6 g/dL; total cholesterol 4.98 mmol/L. BMI: body mass index; CKD: chronic kidney disease; eGFR: estimated glomerular filtration rate; RAASi: renin-angiotensin-aldosterone system inhibitor
