As photochemsyn previously mentioned, a meta-analysis looks at previous research in order to see if there are any interesting conclusions to draw the combined data. As an example, the analysis found that no appropriate studies have been done on doses between 20 - 50 μg, or over 200 μg.

Their notes on how set and setting, and whether or not the participants had ever used psychedelics before affects the experience can also be interesting for a scientist working with LSD. The study also observes that "No direct experimental comparison of the bioequivalence of the two formulations has been made to date", meaning that we simply do not know if LSD base is stronger or weaker than LSD tartrate, or how the ingestion method affects the experience.

This information in tandem with the graphs can be used as inspiration for what kind of experiment to do next in order to better understand how LSD interacts with the brain.

A meta-analysis is a good tool for taking a step back and trying to see if there are any blind spots in the research field.
