  • NOTE: Hazard ratios (HR75) are computed at time Embedded Image for the case Embedded Image, Embedded Image, and Embedded Image. Statistically significant values are shown in bold. “Unit change” denotes the change in the value of each putative biomarker that increases the associated hazard ratio by the reported factor.
