Multivariate predictors of decreased odds of DVT, PE, and VTE
| Variables | OR for DVTa (95% CI, P) | OR for PEb (95% CI, P) | OR for VTEc (95% CI, P) |
|---|---|---|---|
| Body mass index <25 | — | 0.7 (0.5–0.9, <.01) | 0.8 (0.7–0.9, .04) |
| Postoperative dialysis | — | 0.4 (0.2–0.8, .02) | — |
| Outpatient status | — | — | 0.5 (0.2–0.9, .02) |
| Days from admission to surgery | — | — | 0.9 (0.9–0.97, <.01) |
CI, Confidence interval; DVT, deep venous thrombosis; OR, odds ratio; PE, pulmonary embolism; VTE, venous thromboembolic event.
