Melatonin and climactery
S Carranza-Lira, F García López. Medical science monitor : international medical journal of experimental and clinical research, 2000
Topic: Gut, metabolism and diet
Melatonin is a hormone synthesized in the pineal gland from tryptophan. It participates in several biological processes in the human being, such as circadian sleep rhythm, mood, reproductive processes and aging. Melatonin serum levels are increased in childhood and diminish importantly in older people. Serum levels are diminished in patients with insomnia and depressive mood. Experimentally, the melatonin inhibits the growth of mammary tumors in animals. With respect to endometrial cancer and Alzheimer's disease, the information is not conclusive. No changes have been found in melatonin levels in climacterical women. So its use has not fundament in postmenopausal women, however it can only be administered for short periods of time for the treatment of some sleep disturbances.

How this study scored 38/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 21 of the 56 points we could judge it on, which is 38 out of 100.
