TABLE 3.

Application of the Interaction Model at Different Serum Sodium Levels by the MELD Category

MELD
Category		 HR (Sodium =
135 mmol/L)		 HR (Sodium =
130 mmol/L)		 HR
6–8 2.06 2.11 0.973
9–11 0.71 0.73 0.973
12–14 0.43 0.37 1.145*
15–17 0.29 0.25 1.145*
18–19 0.25 0.22 1.145*
20–29 0.23 0.18 1.253*
30–39 0.15 0.11 1.337*
40 0.12 0.09 1.337*

The ratio is significantly (P < 0.05) different from 1 (which represents a significant interaction).
