High cholesterol levels have been shown to be a contribute to heart disease and death for many decades. In the 1970s, scientists used this information to develop a hypothesis that giving a medicine to reduce blood cholesterol levels could reduce the chances of developing cardiovascular disease or dying from cardiovascular disease. They tested a group of people living in Framingham, Massachusetts. This study became known as the Framingham Study, and it is very well known because it did not support the hypothesis. Does this mean that high cholesterol is not a risk factor for heart disease? What does this demonstrate about the scientific process, especially as it relates to human studies? You can find a copy of the study online and read it, if necessary.
