(a) ROC validation of the carotid artery plaque risk assessment chart. The y-axis represents the true positive rate of risk factors. The x-axis represents the false positive rate of risk factors. (b) Calibration curves of the carotid plaque risk nomogram. The y-axis represents the actual diagnosis of carotid plaques, whereas the x-axis represents the risk of carotid plaques. The “ideal” line is the calibration curve, and the "bias-corrected" line represents a correction made to the ideal curve. A curve that is closer to the diagonal dashed line indicates better performance.
