TL;DR: Reliability and Construct validity coefficients confirm the reliability and construct validity of both the AUSCAN LK3.0 and AUS CAN VA3.
Journal Article
Double blind randomized controlled trial of sodium meclofenamate (Meclomen) and diclofenac sodium (Voltaren): post validation reapplication of the WOMAC Osteoarthritis Index.
TL;DR: The WOMAC Osteoarthritis Index was applied as the principal outcome measure in a double blind randomized parallel trial of Meclomen and Voltaren and demonstrated that the relative efficiency of WOMAC was similar to that of the Lequesne and Doyle indices.
