The DCA curve for the 1- and 2-year CSS and OS prediction of SCLC patients with liver metastasis; A 1-year CSS in the training set; B 2-year CSS in the training set; C 1-year OS in the training set; D 2-year OS in the training set. In the figure, the abscissa is the threshold probability, the ordinate is the net benefit rate. The horizontal green one indicates that all samples are negative and all are not treated, with a net benefit of zero. The oblique red one indicates that all samples are positive. The net benefit is a backslash with a negative slope (blue). DCA: decision curve analysis; CSS: cancer-specific survival; OS: overall survival; SCLC: small-cell lung cancer
