I am conducting a meta-analysis and searching pertinent articles in PubMed. The typical scenario is to apply a dedicated search string, and then retrieve between 50 and 5000 citations including the abstract.
Citations, abstracts and ancillary details (eg PMID) can be extracted from PubMed but only as text. Some softwares can support data extraction, such as Zotero or Reference Manager, but they are apparently inefficient or costly.
Is there any more suitable alternative, still free?
