From: A novel method of grading gastric intestinal metaplasia based on the combination of subtype and distribution

  Sensitivity Specificity PPV NPV Accuracy
SDSGIM 89.5% (83.2–95.8) 78.0% (70.9–85.2) 74.6% (66.4–82.7) 91.2% (85.8–96.5) 82.8% (77.9–87.8)
Table 1. Classification 84.2% (76.7–91.7) 82.6% (76.0–89.1) 77.7% (69.5–85.9) 87.9% (82.1–93.7) 83.3% (78.4–88.2)
