Example text

This design, therefore, provides additional information to two separate studies and is a more efficient use of resources, requiring a smaller sample size to obtain estimates with a given degree of precision. 1 (a) Parallel, and (b) Cross-over designs. Study design II Study design 33 PMA14 4/23/05 5:39 PM 14 Page 34 Clinical trials A clinical trial1 is any form of planned experimental study designed, in general, to evaluate the effect of a new treatment on a clinical outcome in humans. Clinical trials may either be pre-clinical studies, small clinical studies to investigate effect and safety (Phase I/II trials), or full evaluations of the new treatment (Phase III trials).

Further refinements of randomization, including stratified randomization (which controls for the effects of important factors), and blocked randomization (which ensures roughly equal sized treatment groups) exist. Systematic allocation, whereby patients are allocated to treatment groups systematically, possibly by day of visit or date of birth, should be avoided where possible; the clinician may be able to determine the proposed treatment for a particular patient before s/he is entered into the trial, and this may influence his/her decision as to whether to include a patient in the trial.

An odds ratio of one indicates that the odds is the same in the exposed and unexposed groups; an odds ratio greater than one indicates that the odds of disease is greater in the exposed group than in the unexposed group, etc. Confidence intervals and hypothesis tests can also be generated for the odds ratio. and therefore the estimated odds ratio = PMA16 4/23/05 5:41 PM Page 41 analysis for matched studies can be found in Chapter 30 (see Conditional Logistic Regression) and in Breslow and Day1.
