PSI Journal Club


Statisticians in the Pharmaceutical Industry's (PSI) Journal Club has been running since 2009, providing a medium for authors of selected papers to present their work to both PSI members and non-members. Sponsored by Wiley, the Journal Club are hosted quarterly by 90-minute teleconferences. Two papers are presented by their authors, followed by questions from the audience.

The following is a list of papers that have been presented at the PSI Journal Club. For access to slides, flyers, video and audio recordings, please visit PSI's website.
