Cox proportional hazards models assessed associations between the GA/HbA1c ratio and mortality or CKD progression (≥ 30% decline in the estimated glomerular filtration rate [eGFR]), adjusting for age, sex, urinary albumin‐to‐creatinine ratio, eGFR, body mass index, haemoglobin and serum albumin. This evidence concerns the gene ALB and chronic kidney disease.
