Nomogram and calibration curves for the prediction of liver metastasis in the patients with GIST. There are five characteristics enrolled in the LIM nomogram (a), and the patient #77784053 is illustrated by mapping its values to the covariate scales. Calibration curves for predicting LIM in the training groups (b) and testing groups (c) are shown in the right side (Bootstrap = 1000 repetitions). The detailed statistics are provided in Additional file 2: Table S2 and Additional file 3: Table S3. Abbreviations: LIM liver metastasis, Pr prediction
