Table 2.

Crude rates of incident diabetes and partially-adjusted relative hazards by serum potassium at baseline. Relative hazards are adjusted for age, sex, race, and center.

	Serum Potassium Levels (mEq/L)
	K < 4.0	4.0 ≤ K < 4.5	4.5 ≤ K < 5.0	5.0 ≤ K ≤ 5.5
Incident cases of diabetes (incident cases not on diuretics)	284 (120)	616 (485)	456 (402)	119 (111)
Person-years	11567	37113	32073	11816
Rate/1000 person-years	24.55	16.60	14.22	11.82
Age, sex, race, center adjusted RH	2.05	1.52	1.37	1.00
(95% CI)	(1.64-2.56)	(1.25-1.85)	(1.12-1.68)	(ref)
