Document Summary
Tell us a lot - don"t tell us incidence or prevalence. To get incidence and prevalence we need the total size of population and duration of observation. If we use the incorrect population we will get inaccurate information. If we include men and women when looking at prostate cancer, we will have artificially inflated the number of people at risk. We compare incidence or odds of the outcome between exposed and unexposed subjects. The control group of the subjects is more important than the study group. Using a certain treatment on patients with arthritis for 4 years. See a reactivation of tb in a small amount of patients to whom you prescribe this treatment. Write up a case series about these 5 patients detailing when they started treatment and when they developed tb - telling stories of patients in an article (descriptive, anecdotes) Important because they can lead to a quantitative study.
