Research Studies on Face Masks

In order to have an informed debate, people need to have a look at studies, or meta-analyses where lots
of previous studies are summarised together, on face masks. There is usually a summary of the findings at the beginning of the study under the heading Abstract.
Although there is some research terminology used that not everyone can understand, these can be looked up. Generally, there is a one or two sentence statement stating the results of that particular study.
However, different studies used different types of masks, and methods.
I googled research study face mask review.
or try other searches like face mask studies, face mask research.

It would allow people to see the scientific basis of the problems of this topic.
