Summary results for primary preoperative rectal cancer nodal (N) staging, Comparative Effectiveness Review Imaging Tests for the Staging of Colorectal Cancer, Agency for Healthcare Research and Quality, 2014
  MRI versus ERUS CT versus ERUS MRI versus CT
Sensitivity (95% CI) MRI: 49.5% (36.0-63.1)
ERUS: 53.0% (39.7-65.5)		 CT: 39.6% (28.1-52.4)
ERUS: 49.1% (34.9-63.5)		 Not calculated
Specificity (95% CI) MRI: 69.7% (51.9-83.0)
ERUS: 73.7% (43.6-91.0)		 CT: 93.2% (58.8-99.2)
ERUS: 71.7% (56.2-83.4)		 Not calculated
Accuracy (OR of getting an incorrect result [95% CI])* 0.882 (0.542-1.408) 1.13 (0.85-1.503) 1.316 (0.709-2.443)
Understaging OR (95% CI)* 0.972 (0.563-1.679) 1.453 (0.854-2.473) 1.743 (1.028-2.957); not robust in sensitivity analysis
Overstaging OR (95% CI)* 0.752 (0.457-1.237) 1.015 (0.571-1.801) 0.498 (0.308-0.806)
Favors No statistically significant difference No statistically significant difference MRI favored for avoiding overstaging
MRI: magnetic resonance imaging; ERUS: endorectal ultrasound; CT: computed tomography; CI: confidence interval; OR: odds ratio.
* OR <1 indicates a lower risk of error in the first imaging modality listed in the column header; OR >1 indicates a higher risk of error in the first imaging modality listed in the column header.
