Table 3. Intra and inter-reader variability.

	Reader 1		Reader 2
	Intra-reader (n = 59)	Inter-reader (n = 70)	Intra-reader (n = 54)	Inter-reader (n = 72)
ZN	1 major error (HFP)	1 major error (HFP)	2 minor errors (1 LFP & 1 LFN)	1 minor error (LFP)
iLED	0 errors	5 minor errors (4 LFP & 1 LFN)	1 minor error (QE)	1 minor error (LFP)
Fraen AFTER	1 minor error (LFP)	5 minor errors (5 LFP)	0 errors	7 minor errors (6 LFP & 1 LFN)
Lumin	3 minor errors (1 LFN & 2 LFP)	1 major error (HFP) and 3 minor errors (1 LFP & 2 LFN)	0 errors	1 major (HFP) & 1 minor error (QE)
Total	1 major & 4 minor errors	2 major errors & 14 minor errors	3 minor errors	1 major & 10 minor errors

Intra-reader variability refers to re-reading of slides by the same reader.

Inter-reader variability refers to re-reading of slides by a second reader.

HFP, high false positive; LFP, low false positive; LFN, low false negative; QE, quantification error.
