Table 5 Performance of the narrow-band imaging-modified Kyoto score according to Helicobacter pylori infection status, % (95% confidence interval)

Group	n	AUC (95%CI)	Optimal cutoff	Sensitivity	Specificity	PPV	NPV	Accuracy
Current infection	114	0.837 (0.762-0.913)	≥ 4	87.9 (80.3-93.3)	49.7 (41.1-58.3)	54.9 (51.9-58.0)	85.7 (83.0-88.0)	64.0 (58.2-69.5)
Past/never infection	111	0.878 (0.812-0.944)	≥ 4	83.8 (75.0-90.0)	65.5 (57.0-73.2)	62.7 (57.1-68.0)	85.4 (80.1-89.5)	73.2 (67.3-78.4)
P for Delong test¹	0.213

¹P value for comparison of the area under the curves between the Helicobacter pylori infection status groups using the DeLong test.

AUC: Area under the receiver operating characteristic curve; CI: Confidence interval; NPV: Negative predictive value; PPV: Positive predictive value.
