Figure 2. The nomogram, calibration curve, and decision curve for predicting the probability of BM for the whole study population. (A) A nomogram that integrates CCRT, RT dose, and PNI in LS-SCLC patients; (B) The calibration curve of the nomogram predicting the incidence of BM; (C) The decision curves of the nomogram predicting the incidence of BM. Abbreviations: BM: brain metastases; CCRT: concurrent chemoradiotherapy; RT: radiotherapy; PNI: prognostic-nutrition index; LS-SCLC: limited-stage small cell lung cancer.
