Baseline values were obtained for:
probability of injury (normal CR), 0.017 (0.01 - 0.075);
angiographic complication rate, 0.026 (0.017 - 0.113);
operative mortality (emergent), 0.185 (0.135 - 0.24);
complication rate (emergent), 0.25 (0.20 - 0.30);
mortality (missed injury), 0.76 (0.74 - 0.97);
operative mortality (late), 0.05 (0.04 - 0.17);
complication rate (late), 0.11 (0.05 - 0.20);
paraplegia (emergent and late), 0.07 (0.01 - 0.24) and 0.01 (0 -0.02);
sensitivity (arc) and specificity (arc), 1.0 (0.9 - 1.0) and 0.95 (0.9 - 1.0);
sensitivity (TEE) and specificity (TEE), 0.86 (0.62 - 1.0) and 0.90 (0.81 - 0.98);
sensitivity (CT) and specificity (CT), 0.67 (0.55 - 0.88) and 0.58 (0.54 - 0.72);
sensitivity (CR), 0.924 (0.89 - 0.983);
and the baseline utility for paraplegia, 0.72.
