Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect risk of stroke.
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 2 studies
There may be a decrease in the rates of strokes among subjects (dyslipidemics) using pharmacological doses of niacin when compared to controls
grade-b - Very High See all 3 studies
There does not appear to be a protective effect of vitamin E on the development of stroke relative to placebo.
grade-c - - See study
The risk of stroke does not appear to be reduced with supplementation of 240mg EGb-761 in older individuals.
