Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect motor control.
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Supplement Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-b Minor Very High See all 3 studies
Acute usage can reduce motor control and fine coordination, but this appears to be an effect that can be subject to tolerance (with tolerant users not seeing any difference following usage of marijuana).
grade-c - - See study
Supplementation of 5mg PRL-8-53 has failed to improve hand motor control following supplementation.
grade-d Minor - See study
Improvement in one study in healthy people. Needs to be replicated.
