Figure 4: Kaplan-Meier plots of EFS and OS of NB patients stratified by levels of soluble biomarkers. EFS and OS of NB patients stratified according to levels of chromogranin ((a) and (b)), sHLA-E ((c) and (d)), and sHLA-F ((e) and (f)) above (black dots) or below (white dots) the ROC cut-off levels. -axes indicate proportion of event-free or alive NB patients, whereas -axes indicate survival time (days or months). P values are indicated where the difference is significant.
