Prevalence of comorbidities and adjusted odds ratios for in-hospital death among adult hospitalizations with a diagnosis of VTE and among those with DVT or PE, NIS, 2010.

aReferent groups were adult hospitalizations without corresponding comorbidity.bWith a diagnosis of DVT only.cWith a diagnosis PE with or without a diagnosis of DVT.dSubgroup with comorbidity are shown (subgroups without comorbidity: n = 153,518 - n for subgroup with corresponding comorbidity).eConfidence interval.fOdds ratios from logistic regression model with backward elimination procedure that adjusted for age (continuous), sex, race/ethnicity, total days of hospital stay (continuous), primary expected payer, major operating room procedure, and all comorbidities in the table without suppressed cells.gEliminated variable not in the final logistic regression model.hHospitalizations with PE and without other diseases in the category were classified as having negative status for the comorbidity.Note: Comorbidities are significantly and positively associated with in-hospital death are bolded.
