Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

| Group 2 | Without Antihypertensive | Participants who received no antihypertensive as a concomitant drug and experienced treatment-related adverse events after having received Amlodipine Tablets or Amlodipine OD Tablets 10 mg/day orally according to Japanese Package Insert at least once. | 72 | 5,509 | OG001 | ClinicalTrials.gov |
