2. Fig 1
Cumulative chest drainage volumes at 4-hour intervals for 24 hours postoperatively. Values in this and subsequent figures are expressed as medians and the error bars represent the 25th and 75th percentiles. ∗Difference between the aprotinin and placebo groups at that stage, p = (EACA = epsilon aminocaproic acid.)

3. Fig 2
Cumulative chest drainage at 4-hour intervals for 24 hours postoperatively in those patients having valve operations in the aprotinin (n = 4) and placebo (n = 5) groups. ∗Difference between the aprotinin and placebo groups at those stages, p = 0.06.

4. Fig 3
Serum D-dimer levels at four stages. The levels were not statistically different at any stage. (EACA = epsilon aminocaproic acid.)

5. Fig 4
Changes in troponin I levels from those at pretreatment. Median (interquartile) pretreatment values were: aprotinin 4.2 ng/mL (2.7,7.5), epsilon aminocaproic acid (EACA) 3.8 ng/mL (2.5, 5.0), and placebo 2.4 ng/mL (1.8, 5.1).
