Comparison of outcomes between urea only–treated and urea-untreated patients

Outcome	Urea-Only Treated, n=12	Urea Untreated, n=12	P Value
Baseline plasma sodium	125 [122–127]	123 [121–125]	NA
Change in plasma sodium by 24 h, mEq/L	2.5 [0–4.5]	−0.5 [−2.5 to 1.5]	0.04
Change in plasma sodium by end of therapy, mEq/L	6 [3.5–10]	5.5 [3–7.5]	0.51
Normalization of plasma sodium, N (%)	4 (33)	1 (8)	0.08
LOS, d	6 [3.5–7]	6 [4–6]	0.74

Data are presented as median [interquartile range] or N (%). NA, not applicable, because urea-treated and untreated patients were matched for baseline plasma sodium; LOS, length of hospital stay.
