Measures6
Calculated by ConductScience from the counts the trial posted to ClinicalTrials.gov.
| Measure | Value | 95% interval, lower | 95% interval, upper | Method | Note |
|---|---|---|---|---|---|
| Risk in group 1 | 0.08 | 0.0411 | 0.15 | wilson | |
| Risk in group 2 | 0.11 | 0.0625 | 0.186 | wilson | |
| Risk difference, group 1 minus group 2 | -0.03 | -0.116 | 0.0546 | newcombe hybrid score | |
| Risk ratio, group 1 over group 2 | 0.727 | 0.305 | 1.73 | log | |
| Odds ratio, group 1 over group 2 | 0.704 | 0.27 | 1.83 | log | |
| Number needed to treat, for one fewer participant with a serious adverse event on Normoxia than on Hyperoxia | 33.3 | from the risk difference interval | the interval includes no difference |

Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Normoxia | Oxygen administration to maintain a hemoglobin oxygen saturation of 95-97% or arterial PaO2 80-110 mmHg during surgery.~Oxygen - normoxia: Titration of FIO2 to maintain normal hemoglobin oxygen saturation (95-97%) | 8 | 100 | EG000 |
| Group 2 | Hyperoxia | Fraction of inspired oxygen 1.0 during mechanical ventilation and 0.8 during cardiopulmonary bypass during surgery.~Oxygen - hyperoxia: Administration of 1.0 FIO2 during ventilation and 0.8 or above during cardiopulmonary bypass | 11 | 100 | EG001 |
