Who created this resource: This is one of two articles published together in the British Medical Journal (BMJ) in 1994 by two very well-known British biostatisticians and educators, Douglas G. Altman (1948-2018), late professor of statistics in medicine at Oxford University, and J. Martin Bland (1947-), professor of health statistics at the University of York.

What does this resource offer
This is the first of two very short 1-page published articles. This one clearly explains what sensitivity and specificity are, how they are calculated, and how to interpret these diagnostic measures. It uses plain language and a small example.
