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 | PP (Per Protocol) | Patients who underwent the study procedure, independent of the success of the procedure and in the absence of major protocol deviations. The analysis of the PP population excludes those subjects for whom a major protocol deviation was identified by the CEC | 630 | 632 | OG000 |
| Group 2 | ITT (Intention to Treat) | All patients who were enrolled in the pivotal phase of the study in which a major protocol deviation was identified by the CEC. | 690 | 692 | OG001 |
