Fig 3 Mirrored histogram displays nominally 6-month follow-up Duke Activity Status Index scores according to whether red blood cells had been transfused. (Blue bars = no blood transfusion; red bars = red blood cell transfusion.)

Fig 4 Empiric probabilities of five grouped follow-up Duke Activity Status Index (DASI) groups at each number of packed red blood cell (RBC) units according to whether platelets were given (yes/no). The solid lines denote with platelet usage; the dashed lines represent no platelet usage.

Fig 5 Relationship between increasing age, recipient of blood transfusion (solid black line) or not (gray line), and the probability of being in the highest follow-up Duke Activity Status Index (DASI) functional category (58.2) based on a low-risk patient and the equation represented by Table 4. The dotted lines represent 95% confidence intervals.
