Table 2 The detection rate of gastric cancer and false negative-gastric cancer n (%)

Scope examinations	Detected GCs	Detected FN-GCs	FN-GCs/GCs
SC-E (n = 6831)	16 (0.23)	4 (0.059)	25.0%
C-E (n = 14807)	94 (0.63)	13 (0.088)	13.8%
P value	0.01	0.48	0.27
SC-E¹ (n = 6657)	16 (0.24)	4 (0.060)	25.0%
C-E¹ (n = 11644)	40 (0.34)	13 (0.112)	32.5%
P value	0.23	0.27	0.75

¹3352 secondary endoscopic examinations that including 54 gastric cancer cases were excluded from a total 21638 endoscopic examinations because most of secondary endoscopic examinations tended to be performed by conventional-endoscope (C-E). GC: Gastric cancer; FN-GC: False negative-gastric cancer; SC-E: Small caliber-endoscope.
