Preoperative Serum Calcitonin Level and Ultrasonographic Characteristics Predict the Risk of Metastatic Medullary Thyroid Carcinoma: Functional Analysis of Calcitonin-Related Genes

Figure 1

Screening for factors associated with prognosis and metastasis in medullary thyroid cancer (MTC). (a, b) Error-rate plot for 1000 cross-validations. (a) LASSO correlation coefficients for all factors of interest in this study. (b) Survival analysis based on the blood flow, calcification, diameter, echo, grade, M, N, and nodule edge as factors that are associated with MTC prognosis. (c, d) Principal component analysis was used to assess the ability of these data to stratify the prognosis and risk of metastasis in patients with MTC.
