  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
