I bought this book to while away time on a plane journey to the USA on holiday, and liked it so much that when I was asked to give an informal introductory Stats talk to a group of doctors in New York, I recommended it to them and worked through the example in Fig 4-2.
The book does a very good job of explaining Franklin's Law (nothing is certain except death and taxes), illustrating it with important problems like HIV tests and DNA testing. The idea that even DNA tests are not infallible will come as news to some! It also discusses cost-benefit issues in diagnostic tests and the way to explain risk in a way that is not misleading, specifically emphasising the value of ARR and NNT over RR reduction.
All in all, the book seems to me an essential contribution to public education, especially for doctors and lawyers.
Most highly recommended.
