Hypothesis: Hierarchical levels of evidence based medicine are wrong

Dear Editor,

I have data to support the hypothesis described in the title of this letter.

Before rejecting the null hypothesis I would like to ask the following open question:
Could you support with data that hierarchical levels of evidence based medicine are correct? (1,2)

Additional explanation to this question:

– Only respond to this question attaching publicly available raw data.
– Be aware that more than a question this is a challenge: I have data (i.e., evidence) which is contrary to classic (i.e., McMaster) or current (i.e., Oxford) hierarchical levels of evidence based medicine. An important part of this data (but not all) is publicly available.

Competing interests: I endorse the principles of open data in human biomedical research.
