Background of the question
A 60-year old man is suddenly unable to talk and half of his body is paralyzed, and sent to the hospital within 12 hours from onset of symptoms. He is diagnosed with an acute ischemic stroke, which the doctor explains is caused by a blocked blood vessel in the brain. He is also informed there is a possible procedure to remove the blockage (called clot retrieval), and that some patients will have an improved outcome because of the clot retrieval. However, this procedure has strict inclusion criteria (rules of selection) and not everyone has the chance to get this treatment.

There are 100 acute ischemic stroke patients within 12 hours from onset shown as 100 faces below in three different colors. Here are five graphs of different scenarios according to different inclusion criteria and anticipated outcome. Please rank how acceptable each scenario is to you if you were the patient or the patient’s family, and answer the following 2 questions.
