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 | Bisoprolol | Bisoprolol was administered at a dose of 5 milligram (mg) once daily for 2 weeks. If the heart rate was less than or equal to 65 beats per minute (bpm) at Week 2, then the initial dose was administered for another 2 weeks (up to Week 4). If the heart rate was greater than 65 bpm at Week 2, then the dose was further increased to 7.5 mg once daily for 2 weeks (up to Week 4). If the heart rate was less than or equal to 65 bpm at Week 4, the increased dose was administered for another 2 weeks (up to Week 6). If the heart rate was still greater than 65 bpm at Week 4, then the dose was further increased to 10 mg once daily for 2 weeks (up to Week 6). If the heart rate was less than or equal to 65 bpm at Week 6, the increased dose was administered for another 2 weeks (up to Week 8). If the heart rate was still greater than 65 bpm, then the treatment was ceased. | 0 | 86 | EG000 |
| Group 2 | Atenolol | Atenolol was administered at a dose of 50 mg once daily for 2 weeks. If the heart rate was less than or equal to 65 bpm at Week 2, then the initial dose was administered for another 2 weeks (up to Week 4). If the heart rate was greater than 65 bpm at Week 2, then the dose was further increased to 75 mg once daily for 2 weeks (up to Week 4). If the heart rate was less than or equal to 65 bpm at Week 4, the increased dose was administered for another 2 weeks (up to Week 6). If the heart rate still greater than 65 bpm at Week 4, then the dose was further increased to 100 mg once daily for 2 weeks (up to Week 6). If the heart rate was less than or equal to 65 bpm at Week 6, the increased dose administered for another 2 weeks. If the heart rate was still greater than 65 bpm, then the treatment was ceased. | 0 | 91 | EG001 |
