IRS construction and validation. a Partial likelihood deviance of different numbers of variables revealed by the LASSO regression model. The red dots represent the partial likelihood deviance values, the grey lines represent the standard error (SE), the two vertical dotted lines on the left and right, respectively, represent optimal values by minimum criteria and 1-SE criteria. b–d Kaplan–Meier curves of OS between high and low IRS groups in the training cohort (b), validation dataset-1 (c) and validation dataset-2 (d); IRS immune risk score, LASSO least absolute shrinkage and selection operator, OS overall survival
