  • MRR, median rate ratio; 95% CI, 95% confidence interval; UACR, urine albumin-to-creatinine ratio; UPR, urine protein-to-creatinine ratio; ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker.

  • a MRR adjusted for patient’s age, sex, race (white versus other), history of hypertension, history of cardiovascular disease, diagnostic cost group relative risk score (continuous) of patients, insulin use, use of Medicare, and eGFR (patient-level variables).

  • b MRR adjusted for variables above, plus teaching versus nonteaching facility, receipt of care from a physician versus nonphysician primary care provider, and the number of primary care visits 1 year before the index primary care visit (facility- and provider-level variables).
