1
Concordance rate between the M-NBI and histopathology was 69.1% for the antrum and 72.7% for the corpus.
2
Diagnostic yield per-patient and per-site was 65% and 53%, respectively.
3
MTB and LBC had sensitivities, specificities, and accuracy of 100/72.1%, 66.0/96.0%, and 81.7/84.9%, respectively. NBI: Narrow-band imaging; M-NBI: Magnifying narrow-band imaging; LBC: Light blue crest; WOS: White opaque substance; MTB: Marginal turbid band; N/A: Not applicable.
