The decision curve analysis (DCA) of prediction models predicting 3-year PFS in training cohort. The X-axis represented the threshold probability that was where the expected benefit of treatment was equal to the expected benefit of avoiding treatment. The Y-axis represented the net benefit. The gray line represents the assumption that all LACC patients gained substantial benefit after CCRT. The horizontal black line represents the assumption that no LACC patients gained substantial benefit after CCRT
