Competing Interests

LS and CG are both full time employees of the charity training the dogs. NJR works primarily for University of Bristol but is also a part-time paid employee of Medical Detection Dogs. SM who did the majority of the analysis has no financial interest in Medical Detection Dogs. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
