Efficacy, acceptability, and tolerability of all available treatments for insomnia in the elderly: a systematic review and network meta-analysis
Acta psychiatrica Scandinavica (2020) · Meta analysis · n=6832
Network meta-analysis of 53 randomised trials with 6,832 older adults (average age 75) covering all treatments for insomnia.
The points come from one 8-week dose-comparison RCT of an aqueous root and leaf extract at 125, 250 or 500 mg a day against placebo in adults with self-reported high stress (PMID 38732539, 131 enrolled, 98 analysed). All three doses reduced perceived stress and were reported as safe, and the authors describe the effect as dose-dependent. The abstract gives no per-dose effect sizes, so the curve shows only that ordering, not how large each step is. It also does not show whether doses above 500 mg add more. Trials of other extracts (root-only extract at 600 mg a day, PMID 23439798, and a 240 mg extract, PMID 31517876) are not on this axis because milligrams of different extracts are not equivalent.
