In this half-day workshop, participants will critically review a paper that has not yet been published as it was initially submitted to the American Journal of Epidemiology. The paper will be sent to participants in advance of the workshop; participants should critically review the materials and come prepared to discuss their feedback. During the workshop, a presentation will be made regarding some of the main points to be considered when preparing or reviewing a manuscript. Small-group work will follow the presentation so that participants can compare their reviews and prepare a consolidated list of critical comments on the paper. Each group will designate a leader who will present the group’s review of the paper to the whole group of participants. At the end of the workshop, participants will receive copies of the manuscript’s AjE reviews, the initial editorial decision, and the final accepted version of the paper. Attendance will be limited to 30 participants.
