Update: Inspired by this Challenge, the journal Physiological Measurement has devoted a focus issue [2012 Sept;33(9)] to the subject of signal quality in cardiorespiratory monitoring, with eleven articles on this topic, including nine written by Challenge participants.

The first of these papers is an introduction to the challenge topic, with a summary of the challenge results and a discussion of their implications.
