Analysis of prognostic factors for PTC. a Univariant CoxPH of risk score and 6 clinical phenotypes (gender, T, N, stage, age, extrathyroidal extension). b Multivariant CoxPH of T, stage and risk score. c A nomogram performed based on prognostic factors found in CoxPH. d A heatmap which showed the risk scores, clinical phenotypes and gene expression (IGF2BP2, GSTM2, MTHFD1 and STT3A) of patient with PTC. A Chi square test was also performed to evaluate the relationships among risk score and 9 clinical phenotypes (*P < 0.05, **P < 0.01, ***P < 0.001)
