Clinical trials randomisation - image description

The illustration shows an example of how people are chosen randomly by a computer to go into the different groups of a trial. This is randomisation. At the top are six differently coloured figures representing the patients who are being entered into the trial. Below them are pieces of coloured paper. Each figure has a correspondingly coloured piece of paper which represents their information. Underneath the papers is an arrow pointing downwards into a computer. This shows the patients’ information being entered into the computer and randomly put into different groups of the trial. Below the computer are two arrows pointing to either side. One arrow points to the three patients who have been put into the control group. This means they will receive the standard treatment. The other arrow points to the three patients who have been put into the trial group. They will receive the new treatment.
