TABLE 2.

Adjusted models for in-hospital mortality and ARDS risk according to the CD4/CD8 T-cell ratio tertiles.

In-hospital mortality	Hazard ratio	CI (95%)		p-value
First tertile (Ref: 1, second tertile)	2.16	0.71	6.58	0.175
Third tertile (Ref: 1, second tertile)	4.68	1.56	14.04	0.006
ARDS	Odds ratio	CI (95%)		p-value
First tertile (Ref: 1, second tertile)	1.58	0.87	2.87	0.131
Third tertile (Ref: 1, second tertile)	1.97	1.11	3.55	0.022

ARDS: Acute respiratory distress syndrome.

Adjusted models. For In-hospital mortality we used a Cox Proportional Hazards model, adjusted for age, sex, comorbidity, and severity of the episode. For ARDS we applied a logistic regression model adjusted for age, sex, comorbidity, and severity.
