3.2.1  Introduction

Here we introduce and explain some important definitions used by The Cochrane Collaboration relevant to maintaining reviews, and their application to the publication of reviews. Section 3.3 deals specifically with the definitions and use of dates in describing events associated with the review. While much of this detailed information is technical, authors will need an understanding of these issues to ensure correct use of terms and dates in their review, and when completing the relevant fields in RevMan.
