ACEi or ARB use among elderly CKD patients with diabetes or proteinuria

Cohort	n	Standard Prompt, n (%)	Enhanced Prompt, n (%)	Intraclass Correlation Coefficient (P Value)	Relative Risk (95% Confidence Interval)
eGFR <60 ml/min per 1.73 m2	5444	1932 (77.1)	2260 (76.9)	0.020 (<0.001)	1.00 (0.96–1.04)
eGFR <30 ml/min per 1.73 m2	483	161 (72.2)	208 (80.0)	<0.001 (0.497)	1.13 (1.03–1.24)

Percentages represent patients with outcome out of the number of patients in the subgroup of interest, irrespective of baseline ACEi/ARB use. ACEi, angiotensin converting enzyme inhibitor; ARB, angiotensin receptor blocker; eGFR, estimated GFR.
