Patient characteristics and relation between rate of change in percentage of predicted oxygen consumption (VO2%) with change in exercise test parameters, initial exercise test parameters and demographic and clinical variables*
| Characteristic | Correlation or Mean ± SD | p Value |
|---|---|---|
| Age at initial exercise test (years) | 0.09 | 0.44 |
| Age at surgery (years) | −0.16 | 0.18 |
| Right ventricular outflow tract gradient (mm Hg) | 0.06 | 0.63 |
| Gender | 0.51 | |
| Female (% point change in peak percentage of predicted oxygen consumption/year) | −0.9 ± 9.4 | |
| Male (% point change in peak percentage of predicted oxygen consumption/year) | −1.8 ± 9.1 | |
| Transannular patch | 0.14 | |
| No (% point change in peak percentage of predicted oxygen consumption/year) | −2.6 ± 9.1 | |
| Yes (% point change in peak percentage of predicted oxygen consumption/year) | −0.7 ± 9.2 | |
| Previous shunt palliation | 0.05 | |
| No (% point change in peak percentage of predicted oxygen consumption/year) | −2.2 ± 9.2 | |
| Yes (% point change in peak percentage of predicted oxygen consumption/year) | 0.7 ± 9.0 |
