Table 2 Association between PE diagnosis by enhanced MDCT with Wells score and unenhanced MDCT findings

From: Unenhanced multidetector computed tomography findings in acute central pulmonary embolism

  OR (95% CI) p-value aOR (95% CI) p-value
Wells score (≥ 4.5 vs. < 4.5) a 1.68 (1.17, 2.41) 0.005 2.10 (0.99, 4.42) 0.052
Number of findings on unenhanced MDCTb 21.11 (4.91, 90.77) <  0.001 26.34 (4.91, 141.29) <  0.001
High attenuation in pulmonary artery (PA) b NA
Main PA dilatation > 33.2 mm b 8.53 (2.15, 33.79) 0.002 10.59 (2.39, 47.02) 0.002
Peripheral wedge-shape consolidation b 2.78 (0.93, 8.27) 0.066 2.79 (0.84, 9.20) 0.093
  1. aOR adjusted odds ratio, MDCT multidetector computed tomography, PE pulmonary embolism
  2. NA: Not applicable since there were no non-PE patients for this finding
  3. aThe multivariate model included age, gender, and number of findings on unenhanced MDCT
  4. bThe multivariate model included age, gender, and Wells score
