This extension to the CONSORT Statement provides a minimum list of essential items, that authors should consider when reporting the main results of a randomized trial in any journal or conference abstract. Clear, transparent, and sufficiently detailed abstracts of conferences and journal articles are important, because readers often base their assessment of a trial on such information. Some readers use an abstract to decide whether to seek more information about a trial. However, in some parts of the world, readers often have access to the abstracts only, so health-care decisions may be made on the basis of abstracts of randomized trials. When a trial is reported at a conference, the abstract might provide the only permanent information accessible to most readers.
A collection of examples on using the CONSORT for Abstracts checklist has been provided as well.
There is no flow diagram for this extension.

The main CONSORT Statement is based on the "standard" two-group parallel design. However, there are several variations to the standard trial methodology, including different design aspects (e.g., cluster), interventions (e.g., herbals) and data (e.g., harms).
To help improve the reporting of these trials the main CONSORT Statement has been extended and modified by members of the CONSORT group for application in these various areas. The resulting CONSORT extensions are presented in this section. This list is, by no means, exhaustive; and work is constantly in progress.
Please note that modifications to the CONSORT checklist or flow diagram that are not developed with the involvement of the CONSORT Group do not have permission to name their work "CONSORT".
Some work, however, has been done to modify the CONSORT Statement without the involvement of the Group. These unofficial extensions of the CONSORT Statement can be found here.
