This randomized, open-label phase IV study compared two menopausal hormone regimens in Mexico. The Wyeth/Pfizer record lists 204 actual participants, postmenopausal women aged approximately 45–55 with vasomotor symptoms, and a completed status in its October 2010 update. 12
One regimen combined 17-beta-estradiol 1 mg with trimegestone 0.125 mg continuously; the other was tibolone. Here, the abbreviation TMG refers to trimegestone. The study concerned symptom control and treatment tolerability in that defined population. 12
Verified comparative symptom changes or adverse-event rates were not recovered from the inspected record. A randomized protocol is not itself evidence that one option is better, and it does not establish that hormone treatment is appropriate for someone with different risks or medical history. 12
