Model 1: stratified by glycemia trial, intensive BP trial, standard BP trial, lipid fenofibrate trial, lipid placebo trial, and network. Model 2: stratified by glycemia trial, intensive BP trial, standard BP trial, lipid fenofibrate trial, lipid placebo trial, and network, and adjusts for demographics: age, female, education, and health insurance. Model 3: stratified by glycemia trial, intensive BP trial, standard BP trial, lipid fenofibrate trial, lipid placebo trial, and network, and adjusts for factors in model 2 and for kidney-specific factors: baseline eGFR, microalbuminuria, and macroalbuminuria. Model 4: stratified by glycemia trial, intensive BP trial, standard BP trial, lipid fenofibrate trial, lipid placebo trial, and network, and adjusts for factors in model 3 and for other baseline clinical factors: systolic BP, body mass index, hemoglobin A1c, smoking status, type 2 diabetes duration, history of heart failure, history of cardiovascular disease (myocardial infarction, stroke, revascularization, or angina), history of retinopathy, and baseline use of medications (angiotensin-converting enzymes, angiotensin receptor blockers, insulin, and thiazolidinedione). ACCORD, Action to Control Cardiovascular Risk in Diabetes; UAlb, urinary albumin; SCr, serum creatinine.
No microalbuminuria, macroalbuminuria adjustment in model 3.
No macroalbuminuria adjustment in model 3.
