Hello everybody,
sorry for cross posting!
I've seen that there are many similar levels of evidence designed. When
looking for the evidence do I have to follow some of those levels of
evidence already made, or can I develop my own depending on the
literature found and it's quality?. If the latter is the case, I guess
that I have to have different levels of evidence for every research
question. Any ideas based on experience?
Thanks a lot.
Julia
