Case Studies 2006

Who can give a presentation?

The Case Studies in Data Analysis sessions will be held at the SSC Annual Meeting in London May 28 - 31, 2006. Each Case Study will be introduced by a subject-matter expert, so that the teams presenting analyses will not have to repeat the background information. It is expected that each team will have 15 minutes to present their results, but this will depend on the number of teams presenting. You could opt for a poster presentation if you prefer.

The sessions are intended for teams of graduate and senior undergraduate students working either with or without faculty mentors. If you think you might want to participate, please let us know by April 15, 2006 (late registration will be accepted if arrangement is feasible).
Contact Peggy Ng if you will be participating in Case Study 1 and Alison Gibbs if you will be participating in Case Study 2. We will need to know the list of names for your team, the university which you represent, and your choice of a platform or poster presentation. We will also need to know if you are giving any other papers at the meeting, to avoid scheduling conflicts.

How to contact us

You will doubtless have questions once you start working on the data. You can ask us; you don’t have to guess the answer! You can direct your questions to us and we will put answers to frequently-asked questions on the web pages. You are free to submit questions in either language, English or French.

Case Studies

Case Study 1: Record Linkage

This study introduces the student to different record linkage methods. Data linkage falls into two large categories: statistical matching and exact matching. In many research and administrative situations the need arises to link two or more data sources together. The student assignment is given in progressively complex steps. First the student will use record linkage techniques to ‘update’ a population registry. Next the student can estimate linkage and error rates.

Case Study 2: Sleep Index

Obstructive sleep apnea is characterized by the cessation of breathing in sleep lasting more than 10 seconds. If left untreated it has been shown to result in an elevated mortality rate as well as decreased quality of life. Recently the healthcare system has mandated that having two nights of diagnostic sleep studies should be discontinued in favour of a single night. It is thus necessary for physicians to supplement the information from sleep studies with a variety of questionnaires in order to minimize missed diagnoses of sleep apnea. The data for this case study were collected from a retrospective review of patient charts from the sleep clinic at Toronto Western Hospital. The purpose is to examine the effectiveness of the Berlin Questionnaire, in combination with other questionnaires and with sleep studies, in diagnosing sleep apnea.
