Heart failure

edit

I have removed your changes to heart failure as one does not use a primary research paper to refute the conclusions of a review. Please see WP:MEDRS.Doc James (talk · contribs · email) 17:13, 26 February 2010 (UTC)Reply

This is the line in specific I was referring too:

Individual primary sources should not be cited or juxtaposed so as to "debunk" or contradict the conclusions of reliable secondary sources, unless the primary source itself directly makes such a claim (see Wikipedia:No original synthesis that advances a position). Controversies or areas of uncertainty in medicine should be illustrated with reliable secondary sources describing the varying viewpoints.

Other concerns are that the studies are of small sample sizes.Doc James (talk · contribs · email) 19:22, 26 February 2010 (UTC)Reply
Here for example is a paper which reaffirms previous conclusions PMID 19854331 so without a proper review what you have added is two small primary research studies which are presented to contradict a review. Find a review for this than feel free to readd. --Doc James (talk · contribs · email) 19:31, 26 February 2010 (UTC)Reply
