A review published in JAMA Psychiatry found that, in trials of antipsychotic medications, the change in response to receiving a placebo had increased significantly between 1960 and 2013. The review's authors identified several factors that could be responsible for this change, including inflation of baseline scores and enrollment of fewer severely ill patients.[32] Another analysis published in Pain in 2015 found that placebo responses had increased considerably in neuropathic pain clinical trials conducted in the United States from 1990 to 2013. The researchers suggested that this may be because such trials have "increased in study size and length" during this time period
In a clinical trial, a placebo response is the measured response of subjects to a placebo; the placebo effect is the difference between that response and no treatment. The placebo response may include improvements due to natural healing, declines due to natural disease progression, the tendency for people who were temporarily feeling either better or worse than usual to return to their average situations (regression toward the mean), and errors in the clinical trial records, which can make it appear that a change has happened when nothing has changed
