It is quite common in a randomized clinical trial (RCT) to
encounter patients who do not comply with their assigned treatment.
Since noncompliance often occurs non-randomly, the commonly-used
approaches, including both the as-treated (AT) and as-protocol (AP)
analysis, and the intent-to-treat (ITT) (or as-randomized)
analysis, are all well known to possibly produce a biased inference
of the treatment efficacy.
This book provides a systematic and organized approach to
analyzing data for RCTs with noncompliance under the most
frequently-encountered situations. These include parallel sampling,
stratified sampling, cluster sampling, parallel sampling with
subsequent missing outcomes, and a series of dependent Bernoulli
sampling for repeated measurements. The author provides a
comprehensive approach by using contingency tables to illustrate
the latent probability structure of observed data. Using real-life
examples, computer-simulated data and exercises in each chapter,
the book illustrates the underlying theory in an accessible, and
easy to understand way.
Key features:
* Consort-flow diagrams and numerical examples are used to
illustrate the bias of commonly used approaches, such as, AT
analysis, AP analysis and ITT analysis for a RCT with
noncompliance.
* Real-life examples are used throughout the book to explain the
practical usefulness of test procedures and estimators.
* Each chapter is self-contained, allowing the book to be used as
a reference source.
* Includes SAS programs which can be easily modified in
calculating the required sample size.
Biostatisticians, clinicians, researchers and data analysts
working in pharmaceutical industries will benefit from this book.
This text can also be used as supplemental material for a course
focusing on clinical statistics or experimental trials in
epidemiology, psychology and sociology.
