Placebo and Nocebo Effects.
Placebo and Nocebo Effects Placebo and nocebo effects (effects of patients’ positive and negative expectations) are powerful and pervasive in clinical practice. Neurobiologic mechanisms, informatio...
Effects of open-label placebos in clinical trials: a systematic review and meta-analysis
OLPs appear to be a promising treatment in different conditions but the respective research is in its infancy, and more research is needed, especially with respect to different medical and mental disorders and instructions accompanying the OLP administration.
Placebo Economics: A Systematic Review About the Economic Potential of Utilizing the Placebo Effect
The state of knowledge about HEEs of placebo interventions is scarce and to gain more visibility and acceptability for placebo interventions, future studies should measure outcomes usable for Hees and costs of interventions, andHEEs should be performed for existing studies if data are available.
Placebos in the era of open‐label trials: An update for clinicians
It is the view that future larger‐scale randomized blinded open placebo trials will benefit physicians and improve patient outcomes.
Can an Open-Label Placebo Be as Effective as a Deceptive Placebo? Methodological Considerations of a Study Protocol
This study will allow us to rule on the non-inferiority of an “educated” placebo compared to a deceptive placebo in the context of an acute painful stimulation.
Placebo and nocebo responses in randomised, controlled trials of medications for ADHD: a systematic review and meta-analysis
Although ADHD medications are superior to placebo, and placebo treatment in clinical practice is not feasible, clinicians should attempt to incorporate factors associated with placebo effects into clinical care.
Placebos Without Deception: Outcomes, Mechanisms, and Ethics.
Why do open-label placebos work? A randomized controlled trial of an open-label placebo induction with and without extended information about the placebo effect in allergic rhinitis
Positive expectations do not contribute to the efficacy of open-label placebos, but seem to have an effect on more global and subjective well-being (mental or emotional quality of life).
Open-label placebo for insomnia (OPIN): study protocol for a cohort multiple randomised controlled trial
This study uses a cohort multiple randomised controlled trial design to compare OLP, CP and no treatment for insomnia and results include treatment uptake and clinically significant response rates, objective and subjective sleep parameters, fatigue, mood, expectancy, treatment satisfaction and side effects.
Open-Label Placebo Treatment: Outcome Expectations and General Acceptance in the Lay Population
Surprisingly, the application of DPs was rated as more acceptable than OLPs, and this result might be explained by indirect effects of treatment expectations.


Is the placebo powerless? Update of a systematic review with 52 new randomized trials comparing placebo with no treatment
A systematic review of 114 randomized trials that compared placebo‐treated patients with untreated patients could not confirm that placebo interventions induce powerful effects.
Effects of placebos without deception compared with no treatment: protocol for a systematic review and meta-analysis
A protocol for the first systematic review and meta-analysis of studies of the effects of non-deceptive placebos compared with no treatment and the methods of delivery used for non- deceptively delivered placebos is presented.
Are Treatments More Effective than Placebos? A Systematic Review and Meta-Analysis
Treatment and placebo effects were not different in 22 out of 28 predefined subgroup analyses, and when all criteria for reducing bias were ruled out (continuous outcomes) placebos were more effective than treatments.
Placebo Use in the United Kingdom: Results from a National Survey of Primary Care Practitioners
Placebo use is common in primary care but questions remain about their benefits, harms, costs, and whether they can be delivered ethically, further research is required to investigate ethically acceptable and cost-effective placebo interventions.
Placebos without Deception: A Randomized Controlled Trial in Irritable Bowel Syndrome
Whether open-label placebo is superior to a no-treatment control with matched patient-provider interactions in the treatment of irritable bowel syndrome (IBS) is tested and placebos administered without deception may be an effective treatment for IBS.
Is the placebo powerless? An analysis of clinical trials comparing placebo with no treatment.
Although placebos had no significant effects on objective or binary outcomes, they had possible small benefits in studies with continuous subjective outcomes and for the treatment of pain.

Frequency and circumstances of placebo use in clinical practice - a systematic review of empirical studies
Although the available evidence is incomplete and confusing at times there can be little doubt that the prevalence of placebo use outside of clinical trials is not negligible and that views and attitudes on placebos use differ considerably among individuals, both health care professionals and patients.
The placebo effect and its determinants in osteoarthritis: meta-analysis of randomised controlled trials
The placebo effect is effective in the treatment of OA, especially for pain, stiffness and self-reported function, and the size of this effect is influenced by the strength of the active treatment, the baseline disease severity, the route of delivery and the sample size of the study.
Open-Label Placebo for Major Depressive Disorder: A Pilot Randomized Controlled Trial
A pilot study investigating the feasibility of conducting trials of open-label placebo in adult outpatients with a primary diagnosis of non-psychotic MDD and the effect size for the main outcome measure (HAM-D-17) was medium, which is larger than typical effect sizes for the drug-placebo difference in MDD RCTs.
