- FIGURE 1.
Graph of average daily volume differences between each method for all 3 generators. Error bars represent SD for each infusion method. Generator 2 was used for 20 d and generator 3 for 15 d.
- FIGURE 2.
Graph of average daily dose differences for each method across all 3 generators. Error bars represent SD for each infusion method. Generator 2 was used for 20 d and generator 3 for 15 d.
