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 | 0.227 | 0.201 | 0.255 | wilson | |
| Risk in group 2 | 0.217 | 0.192 | 0.245 | wilson | |
| Risk difference, group 1 minus group 2 | 0.00943 | -0.0288 | 0.0477 | newcombe hybrid score | |
| Risk ratio, group 1 over group 2 | 1.04 | 0.878 | 1.24 | log | |
| Odds ratio, group 1 over group 2 | 1.06 | 0.846 | 1.32 | log | |
| Number needed to harm, for one more participant with a serious adverse event on High Tranfusion Threshold than on Low Transfusion Threshold | 106 | 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 | High Tranfusion Threshold | Transfusions were administered using a higher threshold hemoglobin value. AKA Liberal Cell Transfusion group. | 206 | 908 | EG000 |
| Group 2 | Low Transfusion Threshold | Transfusions were administered using a lower threshold hemoglobin value. The low threshold values reflect more common practice, so this is considered the 'usual treatment' group. AKA Restricted Red Cell Transfusion group. | 197 | 906 | EG001 |
