High Mean Platelet Volume Associates with In-Hospital Mortality in Severe Pneumonia Patients

Table 3

Relationship between MPV level and in-hospital mortality.

	group
In-hospital mortality	HR (95% CI)
Unadjusted	2.722 (1.552-4.773)	<0.001
Model 1	2.543 (1.438-4.499)	0.001
Model 2	2.268 (1.205-4.271)	0.011
Model 3	2.267 (1.166-4.406)	0.016

Reference group is MPV ≤10.5 group.
Model 1: age and sex.
Model 2: model 1 plus comorbid conditions and clinical data (coronary heart disease, COPD, APACHE II score, mechanical ventilation, vasopressor use, and CRRT).
Model 3: model 2 plus albumin, serum creatinine, and serum urea.
MPV: mean platelet volume; COPD: chronic obstructive pulmonary disease; APACHE: acute physiology and chronic health evaluation; CRRT: continuous renal replacement therapy; HR: hazard ratio; CI: confidence interval.
