Scientific studies (review articles) on the relationship between coenzyme Q10 and disease prevention:
One swallow does not make a summer. A famous Dutch saying that could not be any more obvious. Just because one single scientific study about a certain topic makes certain claims, it does not necessarily mean it is true. On the other hand, a review article (a collection of scientific studies on a certain topic) of randomized, placebo-controlled double blind clinical trials (RCTs) will answer the following question:

• There are different types of scientific studies. In increasing scientific evidence are:

1. Cell culture at petri dishes or in a test tube, also called in vitro study. In vitro is Latin for glass.
2. Animal study or in vivo study. In vivo is Latin for life.
3. Human study or clinical trial. These are studies in humans. There are several human studies. These are:
   1. Case-control study.
   2. Cohort study.
