Transplantation prognostic pie chart. Schematic demonstration of different components of actuarial prognostic assessment before allogeneic HCT. Red indicates disease-specific risk models/factors, blue indicates patient-specific risk models/factors, purple indicates other models/factors, and orange indicates the physician’s perception. Solid colors indicate validated and clinically important tools/factors that should be used frequently in the clinic for prognostic assessment; faded colors indicate academically interesting but clinically less used tools/factors, some of which require further future study to further enhance interest such as geriatric assessment.
