Nomogram for predicting the risk of OS. A Nomogram based on data from 80 patients for predicting the risk of OS; B The calibration curve showed the comparison between the predicted and actual 2-year OS in the internal verification; C ROC curve analysis of the ability of the four factors, namely disease status before UCBT, conditioning regimen, ALB and calf skinfold thickness, to predict OS. The area under the ROC curve was 0.840 (9% CI, 0734–0.948)
