Lack of evidence for many medical treatments
One of the strongest criticism used against an unconventional medical treatment is that it is based only on “anecdotal evidence.”
Well, according to the current New England Journal of Medicine more than half of current recommendations are supported only by “expert opinion” and “anecdotal evidence.”
The following quote is taken from Gary Switzer’s HealthNewsReview blog
Reuters Health reports on the publications:
"Even when following medical guidelines to the letter, doctors often use treatments that have little or no scientific support, U.S. researchers said Monday.
They found only one in seven treatment recommendations from the Infectious Diseases Society of America (IDSA) — a society representing healthcare providers and researchers across the country — were based on high-quality data from clinical trials.
By contrast, more than half the recommendations relied solely on expert opinion or anecdotal evidence."
