Pilot Study on Clinical Effectiveness of Autofluorescence Imaging for Early Gastric Cancer Diagnosis by Less Experienced Endoscopists

Table 2

Interobserver variability for detection of neoplastic lesions with AFI and WL.

κ	AFI; (95% CI)	WLE; (95% Cl)
Experienced endoscopists	0.42; (0.33–0.51)	0.52; (0.43–0.61)
Less experienced endoscopists	0.52; (0.43–0.61)	0.29; (0.20–0.38)

AFI: autofluorescence imaging; WLE: white light endoscopy.
