Visual score and derived R/G ratio*
κ (P)
≥0.54 (Positive)<0.54 (Negative)
Pathology
Positive (HGD and moderate dysplasia)246 (moderate dysplasia)0.68 (P < 0.0001)
Negative (LGD)5 (1 inflammation, 2 squamous metaplasia, and 2 mild dysplasia)35
  • * Biopsy sites graded as visual score 1 (class 3/suspicious) and had R/G ratios ≥0.54 were grouped as positive, whereas those graded as visual score 2 (class 1/normal and 2/abnormal) and had R/G ratios <0.54 were grouped as negative.

  • P < 0.05.
