Cochrane's register of studies and search records
The Cochrane Register of Studies (CRS) functions as a data management tool and a data repository of research studies relevant to healthcare. It is curated by Cochrane contributors who identify and screen records from various sources, including bibliographic databases and clinical trial registries such as PubMed/MEDLINE (CRS has a direct link to PubMed on records which have a PubMed ID number, and the fields in the record can be refreshed with PubMed content) , Embase.com, CINAHL, ClinicalTrials.gov, WHO ICTRP. The CRS has built-in machine learning (the Classifier), which uses the classifications from Cochrane Crowd to help users decide if a study report refers to an Randomized Controlled Trials or Controlled Clinical Trials. The machine learning tools can also be used to help users decide whether a study or study report is within the scope of their Review Group, using the Group's existing register as the basis for the classification. It also has a triage function, which allows users to screen a batch of references within the CRS. It also allows for full-text PDFs to be attached to records and also has sophisticated deduplication tools, where users can create their own filters to deduplicate, or use built-in filters.
