From: A preoperative nomogram predicting risk of lymph node metastasis for early-stage cervical cancer
Calibration plot of the nomogram to predict metastatic lymph node involvement. A Calibration plots of the nomogram for the training cohort. B Calibration plots of the nomogram for the internal validation cohort. C Calibration plots of the nomogram for the external validation cohort. Dashed line = ideal reference value where predicted probabilities match actual probabilities of LNM; solid line indicates performance of the current nomogram; filled dots indicate calculations from a subcohort of the present database
