cote of course there are medical case studies but they are not to be confused with a clinical trial.
A clinical trial will typically be placebo controlled, double blind, randomised and probably multi centred. For example I am on a clinical trial at the moment, I will share a little of the detail if if helps explain the process for those who aren't interested look away now this could get dull
I am on the Promise trial which is for women who have suffered recurrent miscarriage. The aim of the trial is to determine whether or not giving women progesterone in early pregnancy reduces the risk of mc.
The trial is multi centred. So there are many hospitals across the uk and possibly across Europe enrolling women onto the trial. It needs to be multi centred as huge numbers of women are needed to enter the trial.
The trial has entery criteria (all trials do). For me to be accepted I needed to have experienced at least 3 mc, be actively ttc and have had investigations into mc that failed to find a cause (unexplained mc).
I needed to provide informed consent to enter the trial, basically they tell me all the info I'm telling you.
I am entered into the trial and randomised. All trials are (should be) placebo controlled at random. This means that I have been provided with pessaries from the lead investigating hospital (London hosp I forget which one). What is important is that the placebo and the active progesterone pessaries look identical. Neither I nor the medical team know if I am on the placebo or the active drug (really important to remove patient and investigator bias, this is called double blind).
I take the pessaries until week 12 of pregnancy and hopefully carry my baby to term.
My outcome (alive baby, miscarriage or still birth) is recorded.
At the end of the trial period all the women's data is reviewed. What the team are hoping to find is fewer mc in the progesterone arm than the placebo arm. rate of mc of 12% progesterone vs 20% placebo would be a really good result
so that's a basic clinical trial
A case study is a very different beast. Typically case studies are used between medical professionals to highlight interesting cases so other professionals may learn from them. For example a drug could be administered that caused a huge allergic reaction in one of a consultants patients. She would present this to her colleagues and could also publish so that others can learn from the experience.
Consultants will also provide a retrospective analysis of a small group of patients who have undergone a particular treatment. This is used by other professionals as a guide towards improving patient care and could be a move towards a new treatment method.
Purely on AWs selection of patients his case study / trial / research was hugely unethical and flawed.
If anyone is still reading all this sincere thanks for your time.
