Replication - why we need to publish our findings.

The pharmacology research sector is changing to accommodate a need for greater transparency and better standards. The themed articles contained herein explain how Pharmacology Research and Perspectives (PR&P) has responded to this agenda. This issue of PR&P contains three articles that consider the reliability of pharmacological research publications, and approaches to their improvement in this regard. This first article explains the importance of publishing findings that confirm or repudiate published findings (so called "replication" studies). It also emphasizes that PR&P actively encourages submission of such articles, and seeks to oppose the publication bias that favors publication of "positive" findings. The second paper explores some initiatives to publish "negative" clinical findings, including a PR&P initiative. The final paper elaborates a toolkit that can be applied to drug discovery research to facilitate the reliability of findings.
