WHAT DID THE
STUDY ACTUALLY FIND?

Research is more useful when you can see both the finding and the limit. Explore human studies, animal experiments and exposure measurements side by side.

A few words that often get in the way

You don’t need to speak “research.”

A study can be useful even when the answer is incomplete. These four terms help you understand what the authors are saying.

Association
Two things appeared together in the data. That alone does not show that one caused the other. Another factor, or the way the study was done, could help explain the pattern.
No association found
The study did not find a clear link for the exposure and outcome it examined. Read its size, measurements and follow-up before extending that result to other questions.
Statistically significant
The result passed a statistical test under the study’s assumptions. It can still be a small effect, and the test does not rule out bias or other explanations.
Certainty of evidence
How much confidence reviewers place in the finding. “Very low certainty” means the true result could be substantially different from the estimate.

Browse the library

Follow the evidence.

Choose a topic, compare results, then open a source to add it to a specific answer. This is a curated starting collection, not a systematic search of all research.

New to the measurements? Start with power-frequency fields, RF & wireless, infrared or light & sleep.

Turn uncertainty into a useful question

Make a gap specific.

“We need more research” is a starting point. A clear population, exposure and outcome make the request more useful.

Who?

Children? Workers? People with persistent symptoms?

What exposure?

Name the source, frequency, duration and how it would be measured.

What outcome?

Specify a health measure and a realistic follow-up period.

What is missing?

Cite a study’s limitation. Explain how new work would address it.
