Comparison of averaged sensitivity and specificity between C-DP and HDR-DP.

	Mean ± SD (95% CI)		Mean difference  ± SD (95% CI)	value
	C-DP	HDR-DP
Sensitivity (%)	68.0 ± 19.3; [54.2, 81.8]	87.0 ± 13.4; [77.4, 96.6]	19.0 ± 19.7; [4.91, 33.1]	0.014
Specificity (%)	75.0 ± 17.2; [62.7, 87.3]	46.0 ± 28.8; [25.4, 66.6]	−29.0 ± 21.8; [ 44.6, −13.4]	0.002
PPV (%)	75 .0 ± 15.1; [64.2, 85.8]	64.4 ± 15.4; [53.3, 75.4]	−10.6 ± 16.2; [−22.2, 0.9]	0.068
NPV (%)	72.1 ± 12.3; [63.3, 81.0]	79.7 ± 19.7; [65.6, 93.7]	7.5 ± 23.3; [−9.1, 24.2]	0.332

values less than 0.05 indicate statistical significance. SD: standard deviation; CI: confidence interval; C-DP: color optic disc photography; HDR-DP: high dynamic-range concept optic disc photography; PPV: positive predictive value; NPV: negative predictive value. Mean difference is the comparison of each item between HDR-DP and C-DP (HDR − C).
