Our publisher has identified a formatting error in the article "Cardiac hemodynamic activity in pediatric heart transplantation. Is it possible to predict catheterization needs?" In table 2, values of 0 incorrectly appear in the column corresponding to P-values.
The correct table is:
Table 2. Data on pretransplant cardiac catheterizations

| 3 CC | 2 | 5 | |
| 4 CC | 1 | 1 | |
| 5 or more CC | 0 | 5 | |
| CC per person; median (IQR) | 0 (0-1) | 2.5 (1-3.75) | .014* |
