There is a horrible defense of ABM (Anecdote-Based Medicine) in the current issue of JAMA (Journal of the American Medical Association).
Apparently, because there is no evidence to support some things the author believes in, the problem is with the evidence.
For example –
There is no evidence to suggest that hospitalizing compared with not hospitalizing patients with acute shortness of breath reduces mortality.
While R. Scott Braithwaite, MD, MS does appear to realize that it is therefore reasonable to conclude that we do not know if this improves outcomes, he advocates that
ignorance intuition is bliss.
We had thousands of years of blood-letting that was based on Dr. Braithwaite’s flawed reasoning.
We had thousands of patients killed by assuming, based on Dr. Braithwaite’s flawed reasoning that getting rid of ectopic heart beats would improve survival of patients who had already had a heart attack.
Almost every proposed medical treatment does not make it through the FDA’s (Food and Drug Administration) evaluation of safety and efficacy.
When we require evidence, we find that most treatments fall into three categories.
1. Not effective.
2. Not safe.
3. Not safe and not effective.
What evidence satisfies Dr. Braithwaite’s flawed reasoning?
In each case, these hypotheses have been untested and therefore there is no evidence to suggest otherwise, presuming a definition of “evidence” that requires formal hypothesis testing in an adequately powered study.1 
What is reference #1?
The satirical piece about parachutes that was published a decade ago.
Does EBM (Evidence-Based Medicine) really work the way presented in a satire piece?
Evidence based medicine is not restricted to randomised trials and meta-analyses. It involves tracking down the best external evidence with which to answer our clinical questions.
Is it intellectually honest to base criticism of anyone, or anything, on an exaggeration?
If we accept Dr. Braithwaite’s flawed reasoning, yes.
But Dr. Braithwaite’s flawed reasoning is dangerous.
However, deciding to intervene when “there is no evidence to suggest” also may make sense, particularly if the intervention does not involve harm or large resource commitments, and especially if benefit is suggested by subjective experience (eg, the qualitative analogue of the Bayesian prior probability).6 
Dr. Braithwaite’s wishful thinking is encouraging him to experiment on people with no ethical approval and no acceptable documentation for research purposes.
You are Dr. Braithwaite’s guinea pig and he says that it is unethical to withhold a treatment that is based on logical fallacies, such as cherry picking and basing decisions on sample sizes too small to produce any valid information.
Beyond its ambiguity, “there is no evidence to suggest” creates an artificial frame for the subsequent decision. It may signal to patients, physicians, and other stakeholders that they need to ignore intuition in favor of expertise, and to suppress their cumulative body of conscious experience and unconscious heuristics in favor of objective certainty.
Ignore intuition, rather than choose a treatment based on intuition?
Dr. Braithwaite does not go that far, but he does claim that a lack of evidence of harm justifies
abuse treatment by intuition.

Cherry picking, suppressing evidence, or the fallacy of incomplete evidence is the act of pointing to individual cases or data that seem to confirm a particular position, while ignoring a significant portion of related cases or data that may contradict that position. It is a kind of fallacy of selective attention, the most common example of which is the confirmation bias.  Cherry picking may be committed intentionally or unintentionally.
A person travels through a town for the first time. He sees 10 people, all of them children. The person then concludes that there are no adult residents in the town.
