^*Adjusted odds ratios, 95% confidence intervals (95% CI), and intraclass correlation coefficients (ICCs) were computed from random-intercept random-intercept logistic regression that controlled for age, gender, race/ethnicity, admission type, medical co-morbidities and disease severity, tobacco use, admission year, and hospital random effects.

PE, pulmonary embolism; DVT, deep vein thrombosis.
