Measurement Parameters for Three Analysis Techniques

						κ Value (each pair of examiners)
	Sensitivity	Specificity	Accuracy rate	PPV	NPV	1 vs 2	1 vs 3	2 vs 3
VJ	0.49^a	0.92	0.63^c	0.93	0.63	0.58	0.50	0.46
MS	0.86^b	0.88	0.87^d	0.94	0.75	0.50	0.65	0.55
OCT	0.90^b	0.88	0.89^d	0.94	0.81	0.77	0.62	0.53

Different letters indicate a statistically significant difference at the 5% level.

VJ, visual judgment; MS, microscope; OCT, optical coherence tomography; PPV, positive predictive value; NPV, negative predictive value.
