Cases were randomly divided into training and validation cohorts at a ratio of 7:3. The new model was constructed based on the results of Cox proportional hazards model in the training cohort. Comparisons of discrimination between the new model and other models in the training and validation cohorts for FFP prediction were measured by time\u2010dependent area under curve (tAUC) and Harrell's C\u2010index. Calibration plots were constructed to compare the consistency between the predicted and observed estimates of survival probability for the new model in the training and validation cohorts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The new model (IPSPLR) composed of International Prognostic Score (IPS)\u20103 and platelet\/lymphocyte ratio (PLR) provided four distinct risk groups. The IPSPLR showed better discriminative ability when compared with IPS\u20103 and IPS\u20107. The AUC of IPSPLR was consistently higher than that of IPS\u20103 and IPS\u20107 between 12 and 120\u00a0months. The C\u2010index of the IPSPLR was higher than that of IPS\u20107 and IPS\u20103. The calibration plots showed an excellent agreement between the IPSPLR\u2010predicted and observed estimates of 5\u2010year FFP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The IPSPLR is an easily used tool for FFP prediction for newly diagnosed advanced cHL.
