The paper discusses the use of cohort studies, randomized controlled trials, the case series, ecological studies, cross sectional studies and case-control studies. The paper provides a description of these study designs, including their uses, costs and outcomes.

From the Paper:

"There are other studies, however, including the case series. The case series is the most basic kind of study that can be done, and it simply involves the researcher's description of an observed case. In other words, the patient's characteristics and presentation - the story that unfolds as the case is addressed - is all that is used (Goodman, Buehler, & Koplan, 1990). There is no control group, and there are no other patients that are observed. This kind of study is strictly about one specific patient and what he or she is doing at the time of study (Goodman, Buehler, & Koplan, 1990). The case is thoroughly described, though, so that it can be used to gain ideas and for reference in the future.
"This case series type of study has a large margin for error when it comes to bias, though, because it is easy for a researcher to misinterpret something that the patient is doing. Without a control group, this becomes more likely (Yehuda & McFarlane, 1995). The case can provide several plausible factors or scenarios, and the researcher will not know which one of them is correct. It becomes guesswork, which is generally not a good choice where science is concerned. The use of it is limited and should only be used for observation and reference in the monitoring of new patients who seem to have cases that are unusual."
