Serum potassium levels with treatment

	Mean ± SD	Hypokalemia (< 3.5 mEq/L)	Potassium supplementation (≤ 3.7 mEq/L)
Baseline	4.03 ± .22
ASA	4.04 ± .21	0	2 (6%)
CTD	3.64 ± .36*	10 (30%)	18 (53%)
HCTZ	3.72 ± .27*	6 (18%)	17 (50%)

*p < .001 for baseline to on‐treatment; difference in mean CTD versus HCTZ, p = .287.

Hypokalemia (K < 3.5): CTD versus ASA p < .001; HCTZ versus ASA p = .025; CTD versus HCTZ p = .392.

K+ supplementation: ASA versus CTD p < .001; HCTZ versus ASA p = .001; CTD versus HCTZ p = 1.00.
