TABLE 4.

Mortality Rate Ratios by Quintiles of the Mental Component Summary

	Mental Component Summary					P Value for the Trend^†
	Quintile 1 (11–30.9)	Quintile 2 (31–39)	Quintile 3 (39.4–46)	Quintile 4 (47–54.2)	Quintile 5 (54.4–70)	P Value for the Trend^†
Rate ratio (95% CI)	1.6 (0.6–4)	1.2 (0.4–3)	1.8 (0.7–5)	0.9 (0.3–2)	1.0	0.22
Adjusted rate ratio (95% CI)^*	1.7 (0.7–4)	1.1 (0.4–3)	1.1 (0.4–3)	0.8 (0.3–2)	1.0	0.16

Adjusted for age, gender, Model for End-Stage Liver Disease score, and liver transplantation.

^†

The linear trend in the hazard ratio was tested by the introduction of the value of the quintile as a continuous variable in Cox’s model.
