From: C2 pars interarticularis length on the side of high-riding vertebral artery with implications for pars screw insertion

Fig. 3

(A) A histogram showing distributions of C2 pars interarticularis length in subjects with (light blue) and without (light peach) high-riding vertebral artery (HRVA). The black dashed line indicates an optimal cut-off point of 16.06 mm above which the HRVA is unlikely. (B) A receiver operating characteristic (ROC) curve evaluating the discriminative performance of the C2 pars length measurement for HRVA detection. The selected cut-off of 16.06 mm achieves sensitivity and specificity of 96.5% and 99.3%, respectively. Created in RStudio.
