Or-logic‡	0.946 (0.013)	0.03	0.734 (0.042)
SVM‡	0.954 (0.012)	0.002	0.777 (0.039)

^*P-values were calculated in comparison to optic disc horizontal integrated rim width, the single scan with the highest AROC value.

^†There were no significance differences among the combined variables.

^‡Classification of the six diagnostic variables included three variables from optic disc scan (horizontal integrated rim width, vertical integrated rim area, and vertical cup/disk ratio) and the other three from peripapillary RNFL scan (overall average, inferior and superior quadrant RNFL thicknesses). SE, standard error.
