We studied the effect of placebo treatments by reviewing 202 trials comparing placebo treatment with no treatment covering 60
healthcare problems. In general, placebo treatments produced no major health benefits,
although on average they had a modest effect
on outcomes reported by patients, such as pain.
The results of this review do not imply that no-treatment control
groups can replace placebo control groups in randomised clinical
trials without a risk of bias
Låter lite lovande dock! Smärta gör ont!
Verkar ha varit lite svårt med concealment.
