Decision curve analysis for the chemotherapy efficacy prediction nomogram. (A) The red line represents the chemotherapy efficacy prediction nomogram of the training cohort. When the threshold probability is between 1% and 58%, the nomogram has a relatively good net benefit. (B) The blue line represents the chemotherapy efficacy prediction nomogram of the validation cohort. When the threshold probability is between 4% and 67%, the nomogram has a relatively good net benefit.
