Association between Axial Length to Corneal Curvature Radius Ratio and Myopia in Adult Patients

Table 4

Area under ROC curve of AL and AL/CR.

Variables	AUC	95% CI	Specificity	Sensitivity	Youden’s index
AL (mm)	0.830	0.769–0.900	0.770	0.738	0.508
CR (mm)	0.502	0.415–0.589	0.484	0.569	0.053
AL/CR	0.896	0.851–0.941	0.672	0.954	0.626

AUC: the area under ROC curve; SE = spherical equivalent (D); AL = axial length (mm); AL/CR = axial length to corneal curvature radius ratio.
