Variable	No. of Patients	No. of Patients With at Least 1 Follow-up Serum Potassium Measurement	No. of Patients With at Least 1 Serum Potassium Measurement >5.5 mEq/L	No. of Patients With at Least 1 Serum Potassium Measurement >6.0 mEq/L	Time (mo) From Randomization Until First Recorded Serum Potassium Measurement >6.0 mEq/L
All patients	1094	1053	50	15	5.16
All ACEI-treated patients	436	417	29	8	5.16
All ACEI-treated patients with a GFR ≤40	148	139	22	7	5.16
All ACEI-treated patients with a GFR >40	288	278	7	1	14.36
All ACEI-treated patients with a BMI ≤25	80	75	10	4	6.64
All ACEI-treated patients with a BMI >25	356	342	19	4	5.16

Abbreviations: ACEI, angiotensin-converting enzyme inhibitor; BMI, body mass index (calculated as weight in kilograms divided by height in meters squared); GFR, glomerular filtration rate.

SI conversion factor: To convert potassium to millimoles per liter, multiply by 1.0.
