Impact of KDIGO 2012 guidelines on frequency of UACR testing during follow-up. Numbers of tests inferred from the number of days with a test result during follow-up post-index. UACR data were not available from before 2012 in LCED. Data are rates with 95% confidence intervals, calculated according to the method reported by Ulm, K.²⁶ CPRD, Clinical Practice Research Datalink; KDIGO, Kidney Disease: Improving Global Outcomes; LCED, Limited Claims and Electronic Health Record Dataset; UACR, urinary albumin-to-creatinine ratio.
