From: Preoperative nomogram for the identification of lymph node metastasis in early cervical cancer
Performance of the nomogram for predicting LNM in patients with early cervical cancer. (A) After 1000 repetitions, the bootstrap-corrected concordance index of the model was 0.878 (95% CI, 0.833−0.917) in the model-development cohort. (B) In the validation cohort, the bootstrap-corrected concordance index of the model was 0.825 (95% CI, 0.736−0.895). (C) Calibration plots of the nomogram for the model-development cohort. (D) Calibration plots of the nomogram for the 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; vertical bar indicates 95% CI.
