Here is what you have written about this peer reviewed journal and I quote "Just because a journal is peer-reviewed etc does not implicitly give it the kudos to be used by us". So before removing any article/source, read it and get it reviewed from others and then decide whether to remove it or not. No matter even if the study is old ABO blood grouping still exists and this study was based upon very sound scientfic experiment of ABO blood grouping. I do not see any reason that why a scientific study which provides info about the link of Sainis had to be removed.
