"If we learn from them, these seemingly disappointing results may be extremely helpful in curtailing harms to patients and cost to the health care system."

According to Dr. Ioannidis, it is just as important to promote and disseminate knowledge about ineffective practices that should be reversed and abandoned. Given the widespread attention that practice guidelines typically receive, particularly when published by authoritative individuals or groups, he questions whether a generally higher level of evidence should be required before these guidelines are recommended and can impact clinical practice.

"Finally, are there incentives and anything else we can do to promote testing of seemingly established practices and identification of more practices that need to be abandoned?
