MPO and deep vein thrombosis: Multivariate logistic regression analysis confirmed that MPO-DNA (Odds Ratio, OR = 11.58, 95% CI: 3.75–35.73, Probability Value, p < 0.001), CitH3 (OR = 1.11, 95% CI: 1.05–1.17, p < 0.001), cell-free DNA (OR = 1.02, 95% Confidence Interval, 95% CI: 1.01–1.02, p < 0.001), and neutrophil (OR = 1.67, 95% CI: 1.14–2.44, p = 0.008) were all independent risk factors for DVT in hHcy patients.
