Heat maps for prediction of all-cause mortality, composite fatal/non-fatal cardiovascular disease (CVD), fatal CVD and end-stage kidney disease using eGFRcys and albuminuria (urine albumin:creatinine ratio; uACR) for estimated glomerular filtration rate (eGFR) based on creatinine (eGFRcr; top), eGFR based on cystatin C (eGFRcys; middle) and eGFR based on creatinine and cystatin C (eGFRcr-cys; bottom). No data were available for those with eGFR >90ml/min/1.73m2 and uACR >3mg/mmol. Otherwise, hazard ratios adjusted for atherosclerotic risk factors (age, sex, ethnicity, systolic and diastolic blood pressure, antihypertensive medications, statin use, smoking, diabetes, total and high-density lipoprotein cholesterol) were ranked 1-13 (1 being the lowest risk), and heat maps were colour-coded for all outcomes: 1-4 (green), 5-7 (yellow), 8-10 (orange), 11-13 (red).
