Module summary
New drugs and other treatments frequently appear on the market. However, before this stage, much research is carried out on a drug's effectiveness; this may often be measured in relation to other existing treatments. Issues involved include how to collect reliable data which is truly representative - without treating humans as guinea pigs. In medical trials (for example, heart transplant students) the success of the outcome may only be measurable some time later, so an analysis of the survival times can be carried out.Objectives
To provide an introduction to statistical methods of specific interest in medical applications.On completion of this module, students should be able to:
(a) carry out appropriate nonparametric tests;
(b) describe various types of clinical trials;
(c) understand different sampling methods;
(d) carry out parametric and nonparametric survival analysis.
Syllabus
New drugs and other treatments frequently appear on the market. However, before this stage, much research is carried out on a drug's effectiveness; this may often be measured in relation to other existing treatments. Issues involved include how to collect reliable data which is truly representative - without treating humans as guinea pigs. In medical trials (for example, heart transplant students) the success of the outcome may only be measurable some time later, so an analysis of the survival times can be carried out.
Topics covered include:
1. Design of medical studies. Double-blind randomized clinical trials; cross-over designs; cross-sectional, cohort and case-control studies; bias, confounding; observation studies.
2. Nonparametric tests. Mann-Whitney; Wilcoxon; Kolmogorov-Smirnov.
3. Epidemiology. Rates of disease; incidence and prevalence; risk and odds.
4. Survival analysis. Parametric models; Kaplan-Meier estimator.
