Anyone interested in the history of moves through contingency tables, survival But to engage successfully, communication statistics will know that much has been data, the normal distribution, regression skills need to be honed. This issues in epidemiology. This makes the ith edition a techniques, which are used to acknowledge recollections and advice.
There are valuable resource for those who prefer and to respond constructively to diicult some contributions that set out current learning by practice as well as those who like questions. Sometimes, I had Chapter 19, for example can be light on Useful guidance is also given on how to the feeling of an unpublished paper sneaking citing supporting literature from recent prepare and deliver presentations and how to out via the pages of this book, but fortunately years.
It would be ideal for the sixth edition, use social media to communicate efectively. This made me laugh out loud and should and multiple outcome measures. This is an excellent book. There is some be posted on the walls of all conferences.

By Pyae Phyo Aung. It is generally a comprehensive text that covers the main statistical methods commonly used in the medical literature. This introductory book appears to be targeted at statisticians and clinicians involved in medical research. However, it is difficult to appeal to both. While the authors have attempted to reduce the amount of algebra and technical statistical language, there is still a significant quantity of it throughout the book; so, many non-statisticians are likely to struggle with many of the sections.
Calculating results by hand can be a useful tool for teaching some people, particularly those who are quite numerate. But going through the algebra for many others can often be daunting for example, see page , and occasionally lead to errors if attempted by hand. With modern computers and several statistical software packages available, knowing the details of how to calculate statistical measures and test values becomes much less important for clinicians, compared with understanding which tests to use and how to interpret output correctly.
Given this, I would have preferred many more examples and their interpretation, and less algebra. On the other hand, medical statisticians, particularly newly qualified ones, would find much of the book useful, as it allows them to have a greater knowledge of how various statistical measures are calculated. The book covers many of the topics likely to be encountered in journals — data that involve counting, data that involve taking measurements on people or objects, the normal distribution, summary measures such as means and relative risks , survival analysis, regression and correlation, analysis of variance, clinical trials, observational studies, sample size estimation and diagnostic tests.
There are some useful discussions on topics that are not commonly covered in many similar textbooks. For example, when handling multiple outcome measures in clinical trials, researchers need to be more cautious about automatically adjusting P -values for multiple comparisons — this is something that is often currently done but perhaps should not be, as the authors indicate Chapter Another useful summary was on the comparison of historical and randomised controls when evaluating treatments Chapter Sections like these contribute to the key strengths of the book.
Some topics could have been covered better. For example, checking whether a variable is Normally distributed Chapter 9 , which is fundamental to the application of many statistical tests, is recommended by looking at a histogram — a useful approach when there are many values in the data set.

However, there are only 33 values in the diagrams in Figures 9. From experience, a normal probability plot where the values should lie approximately along a straight line is much easier to examine, regardless of the number of observations, and so could have been described as well as a histogram. Another example is in Chapter 22, Diagnostic Tests.
The definition of likelihood ratio sensitivity divided by one minus specificity is correct when the diagnostic test variable is categorical or when one is interested in the overall discriminatory power of the test. However, many screening and diagnostic tests have a continuous measurement with a normal distribution with or without appropriate transformation , and we are often interested in estimating the risk for an individual. To do this, the other definition of the likelihood ratio is the height of the normal curve for affected individuals divided by the height of the curve for unaffected individuals, at a given value.
