Table 2 Comparison between CT and Digital Subtraction Angiography (DSA) findings with or without contrast extravasation in pelvic trauma patients who underwent embolisation

	CT + ve	CT –ve	Total	Diagnostic Statistical Evaluation of Trauma CT
DSA + ve	10	9	19	Sensitivity = 90.9% (95% CI = 58.7–99.8%)
DSA –ve	1	4	5	Specificity = 30.8% (95% CI = 9.1–61.4%)
Total	11	13	24	PLR = 1.3 (95% CI = 0.9–2%)
