System Status System has been in development for over 3 years Website launched in June 2012 Hosted on the AHRQ server Trademarked as Systematic Review Data Repository (SRDR™) SRDR is committed to a policy of open access. All completed systematic review projects deposited in the SRDR archive are publically available under the terms of a Creative Commons license Current data contributors are EPCs and other participating organizations (e.g., Cochrane, GIN, NICE) 7

System Status # of users/projects: Current data contributors are EPCs and other participating organizations (e.g., Cochrane, GIN, NICE) There are approximately ongoing projects in the system and over 200 certified users. Features: Interfaces for creating abstraction forms and abstracting study data are in place, with improvements being continually implemented Tools for data retrieval/summarization and sharing have been developed, with new features in the pipeline Users support: Training materials including user manual, instructional videos, and an FAQ are available in the Help section linked to the SRDR homepage 8 8 SRDR Quarterly training #3 November, 2013

9 System Structure Project: All data deposited within the SRDR are organized as individual projects. A project contains all information related to one systematic review (e.g., extraction forms, key questions, extracted studies, etc.) Key Question(s): The specific scientific queries an SRDR project is intended to address. All projects must include at least one key question Extraction Form: The user-defined dialogue by which collaborators extract data from relevant publications into an SRDR project Study: An individual publication extraction, consisting of one instance of a filled out extraction form 9

Data Export Tool 15SRDR Quarterly training #3 November, 2013

2 export options 16SRDR Quarterly training #3 November, 2013

Simple data export tool Complete data set is exported to Microsoft Excel Worksheets divide the document into sections of the associated extraction form One file is exported per extraction form Each study data may be represented by one or more rows in the spreadsheet The Excel is storable and can be exported into Access A refreshed copy of each project is cached for download every 10 minutes Each download will have a timestamp indicating the time of last update 17 SRDR Quarterly training #3 November, 2013

Advanced data export tool Filter export table based on specific study attributes Choose desired data fields for inclusion Great for summary table creation Example: – Give me all RCTs – Containing Outcome A – Containing Arms A and B – Limit the output table to Mean and Standard Deviation Matrix Filtering expedites the process of finding interesting combinations of attributes – Study counts show prevalence of attributes in real-time 18 SRDR Quarterly training #3 November, 2013
