Few people know, but there is a real one hierarchy of scientific evidence. It’s about a pyramid structured in several levels ranging from scientific source simpler to the most credited. Each level, starting with the lowest, is subordinate to the next and, of course, each higher level plays a more important role than the lowest.
Why is it important to know this structure? Because it is thanks to her that it is possible to understand what theories should be referred to when talking about the effectiveness or not of More expensive.
To understand precisely what it is, Fabio Duranti showed a live graphic that specifically explains the usefulness of this system. with Francesco Vergovich, here is the video of his speech in ‘A special day’.
Do you really think that the mask protects you from Covid? ▷ See what the highest scientific level says
“How does scientific research work? With a pyramid. At the highest point is the most important study, the most striking scientific evidence, the indisputable that as such cannot be questioned by an underlying study because it is of less scientific evidence. The lowest point is observational studies, single patient studies. The higher your level, the more important the study. What is the most important study? The meta-analysis on randomized controlled trials.
An important part of science believes that these same rags on the face are the source of the infection. Instead, these gentlemen want you to wear it even when you’re alone with the dog in the park. Randomized meta-analysis studies from the 1950s to 2020 tell us that the mask does not work to stop the flu and coronaviruses and that indeed precisely because its use must be controlled in a certain way it can be seriously harmful.
Proponents of masks simply don’t have the highest levels of scientific evidence to back up their arguments. They can only cite low-level retrospective observational science studies.
I wonder: why are we forced to enter a TSO on the basis of studies that are denied by the highest level of scientific knowledge? I ask these great dictators of 2020: but why do they want to do this to us? “
