Table 2:

κ values and their confidence intervals for 3D DIR, based on nerve segments in the group of patients with MS

3D DIR (No. of Valid Cases)	Symmetric Measures
3D DIR (No. of Valid Cases)	Value MoA (κ)	Asymp. SE^{^a}	Approx. T^{^b}	Approx. Sig.	Exact Sig.	95% CI
Retrobulbar (190)	.942	.023	15.091	.000	.000	0.896–0.987
Canalicular (190)	1.000	.000	15.891	.000	.000	1.000–1.000
Prechiasmatic (190)	.704	.065	13.886	.000	.000	0.576–0.832
Chiasm (95)	.918	.081	10.084	.000	.000	0.759–1.077

Note:—MoA indicates measure of agreement; asymp. SE, asymptomatic standard error; approx., approximative; sig., significance.
↵a Not assuming the null hypothesis.
↵b Using the asymptomatic SE assuming the null hypothesis.
