Introduction
As the text points out, causal  reasoning is used in clinical studies. As a professional in the health  field, you will undoubtedly be referring to cause/effect studies for the  rest of your professional life. In this discussion, you are asked to  expand and deepen your understanding of clinical studies.

In 1999, a study on the causes of myopia appeared in the prestigious journal Nature (Quinn). The study received wide-spread publicity in leading newspapers, such as the New York Times, and on television outlets, such as CBS and CNN. Within a year, another article in Nature followed up the 1999 study (Zadnik et al., 2000). The studies had dramatically different findings.

Initial Post Instructions
