Clinical significance of Ki-67 in patients with lung adenocarcinoma in situ complicated by type 2 diabetes

Figure 4 Receiver operating characteristic curve for Ki-67. The y-axis presents sensitivity (true positive rate), and the x-axis represents 1-specificity (false positive rate). The curve assesses the diagnostic performance of Ki-67, and the area under the receiver operating characteristic (ROC) curve (AUC) is 0.9112, indicating a high level of accuracy. The dotted red line represents a random guess (AUC = 0.5), and the blue ROC curve greatly surpasses this line, illustrating that Ki-67 has strong predictive power in this context. AUC: Area under the receiver operating characteristic curve.
