Table 2: Mean change in serum potassium per 10 mEq of potassium administered.

Dosage Route	Change in serum potassium ± S.D. (mEq/L)
Intravenous and Oral (N = 260)	0.13 ± 0.11
Intravenous (n = 89)	0.14 ± 0.14^*
Oral (n = 171)	0.12 ± 0.08^*

^*p = 0.12 for difference between intravenous and oral potassium groups.
