Thank you so much sir for the detailed answer. It has cleared my concept. Please suggest, can I use electronic word of mouth and advertising communication as verbal placebos/nocebos instead of using a tangible product? I want my participants to consume computer mediated information as a placebo/nocebo instead of actual product. Again thank you for the help.

Hi, Safeena!

By placebo/no placebo, you mean a scenario with a treatment (for example, persuasive communication), and a neutro scenario, right? In marketing you don't need to use tangible products to manipulate scenarios, you can do it by manipulating the message of an ad, for example, or, in case of social media, you can 'simulate' a post and manipulate its comments.

I don't know if I answered to your question, but I hope so.

Hi Renata Martins , Thank you so much. Yes I was looking for the same answer. I will really appreciate if you can share a similar research where it has been used. I am also searching for it.

Not sure if it will help but may give some ideas.... We manipulated anxiety around the choice of generic medicines citing some work on nocebo effectsin Health Promotion International:

Nickel, Not Nocebo, as the cause of High Serious Adverse Reactions in Placebo recipients used in Covid-19 Vaccine Trials

During trials of Covid-19 vaccines, there have been attempts to explain the observed high level of Serious Adverse Events in volunteers who received Placebo jabs.

Nocebo Effect describes a situation where a negative outcome occurs due to a Belief that the intervention will cause Harm. I regard that highly unlikely in people who rolled up their sleeves as volunteers. Are any readers aware of Mandatory jab trials where people were coerced into accepting one or more Placebo jabs?

I attach a SEM picture of syringe needle tip that can be expected to leave some stainless steel in your arm if some of the flakes formed during manufacture break off, presenting a Nickel Hazard.

Numerous researchers are ignorant of the fact that injection with Sucrose also cause allergic reaction in some people.

What statistical method should i use?

It is about an experimental study, where subjects were tested twice at baseline (without supplementation) and after a week with the supplemented and placebo groups.

Each test consisted of measuring some variables at rest, followed by a load test, and then re-measuring the variables at a fatigue state.

I'm finishing a double master in plant sciences and plant biotechnology at Wageningen University & Research. My specialisations are functional plant genomics and phytopathology and entomology, with a minor in nematology and one still to define (around biophysics and omics).

I did a thesis in nematology at the ETH Zurich, one in plant molecular biology at INRAE (French national institute for Agro-Environmental research) and one still to define at SLU (Swedish Agricultural University).

I'd like to pivot toward policy making, but I only have a few courses about transversal skills such as "Negotiation skills", "Communication & Persuasion", "Scientific Writing" etc. and none about policy itself.

Any suggestions on how to pivot to policy making? I saw that there are PhD about it, but I'm not sure to be qualified for them. How could I increase the chances of being admitted to one without pursuing another master?

How to understand placebo and control ?

I don't quite understand what's the difference. In what cases we use placebo? and in what cases we use control group? It will be better if you could answer with an example.

Hi everyone,

I would like to conduct A network meta-analysis to compare two interventions. However, my included studies are indirect comparison (compare intervention 1 or 2 with placebo). Could you tell me that it is possible to do it? Which references I can cite? (I use R for statistical analysis).

Thanks for your helps!

Is PRP a placebo or effective?

There are many studies on the effect of PRP in literature, with almost half of them indicating a placebo effect and the other half indicating effectiveness. From what I understand, the concentration of platelets in PRP is important. Is there anyone who knows about this topic or has researched it?
