First paragraph (this article has no abstract)
Rodriguez-Lopez and colleagues  describe a replication study of our previous association between osteoarthritis (OA) and asporin . The authors were unable to find this association in the Spanish population and question the association we found in the Japanese population. Their report also contains an interpretation of two previous papers on the same topic [3,4] that differs from those of the original study authors. We have concerns about their interpretation of data and about the conclusions drawn.
