Sample size re-estimation in paired comparative diagnostic accuracy studies with a binary response
BACKGROUND The sample size required to power a study to a nominal level in a paired comparative diagnostic accuracy study, i.e. studies in which the diagnostic accuracy of two testing procedures is compared relative to a gold standard, depends on the conditional dependence between the two tests - the lower the dependence the greater the sample size required. A priori, we usually do not know the...
متن کاملSample size estimation in epidemiologic studies
This review basically provided a conceptual framework for sample size calculation in epidemiologic studies with various designs and outcomes. The formula requirement of sample size was drawn based on statistical principles for both descriptive and comparative studies. The required sample size was estimated and presented graphically with different effect sizes and power of statistical test at 95...
متن کاملBayesian Determination of Sample Size in Longitudinal Studies with Binary Responses Using Random Effects Models
Sample size determination is important in all statistical studies including longitudinal studies. This is usually done by considering a target power to reduce the costs of sampling. Choosing the right sample size using efficient methods, ensures that the researcher achieve goal of the study, by spending the least amount of energy, time and money. In this article, using a method based on simulat...
متن کاملSample Size Re-estimation for Binary Data via Conditional Power
We extend Lan and Trost’s (1997,1999) conditional power approach for interim sample size re-estimation to binary data for clinical trials with a noninferiority objective. If conditional power is used to extend a trial, the α level will be inflated. On the contrary if it is used to stop a trial early to claim futility, the α level will be reduced. If inflation does not exceed deflation, then the...
متن کاملSample size re-estimation in clinical trials.
Adaptive clinical trials are becoming very popular because of their flexibility in allowing mid-stream changes of sample size, endpoints, populations, etc. At the same time, they have been regarded with mistrust because they can produce bizarre results in very extreme settings. Understanding the advantages and disadvantages of these rapidly developing methods is a must. This paper reviews flexi...
