“…Table 3 shows rates of severe bleeding, sensitivity, specificity, and likelihood ratios determined by predictive scores. The rates of severe bleeding with 0, 1, 2, 3, 4, and ≥ 5 predictors were 2.0%, 10.0%, 18.3%, 34.8%, 51.6%, and 75.7%, respectively (P < 0.001 for trend). The AUC of the score was 0.77 (95% CI, 0.73-0.82; Figure 2).…”
