Evaluation of death certificate-based surveillance for traumatic brain injury--Oklahoma 2002.

How many joints in the hands and wrists should be included in a score of radiologic abnormalities used to assess rheumatoid arthritis?

Numerous methods for reading abnormalities of rheumatoid arthritis in hand and wrist radiographs have been proposed over the past several decades. There are many differences among these methods, one of the more striking of which is the variation in the number of joints that are scored. In this study, we tested the number of joints that need to be read in order to represent abnormalities accurately and reproducibly, using the scores of multiple observers.
