Table 1.

Cutoff values: a significant difference was observed in sensitivity and Az value receiver operating characteristic (ROC) curve between OCT and radiography (p < 0.05), whereas no such difference in specificity was shown. Different superscripts letters indicated significant difference.

Notes: Cutoff values: a significant difference was observed in sensitivity and area under receiver operating characteristic (ROC) curve (Az) between optical coherence tomography (OCT) and radiography (p< 0.05), whereas no such difference in specificity was shown. Different superscripts letters indicated significant difference.
