Cochrane systematic reviews are often perceived as inaccessible. One of the main activities of the Norwegian branch of the Cochrane Collaboration is to develop ways to present the results of Cochrane reviews so that they are easier to use. In this paper we describe four main principles that underlie this work, and several of the document formats we have helped produce. Our overarching principles: 1) Information should be understandable for people who do not have expert knowledge about research methodology. When it comes to understanding the results of systematic reviews, we have experienced that the biggest difference is between researchers and non-researchers and to a lesser extent between health personnel, patients and policy makers. 2) Information should be presented in a neutral form. 3) Information should be developed using a user-oriented approach. This involves us collecting responses from the end users in our developmental work and making the necessary adjustments in several phases. 4) The information structure should follow the "1:3:25 principle" where the information is structured in several layers, with increasing level of detail. In this paper, we describe several of the document formats that we have helped develop, including Summary of Findings tables, where we present the results of Cochrane reviews in tables; a plain language summary format where the results are presented as text-based summaries written for a broad user group; SUPPORT summaries written for policy makers; and DECIDE Frameworks, where the results are presented together with other information that may be relevant in a decision making process.
