If you're adding columns in the Find papers workflow, filter to papers that have PDFs, so that Elicit has more information to work with:

When Elicit has access to the PDF of the paper, Elicit can search for information from the entire paper. If Elicit does not have access to the PDF for the paper, Elicit can only pull information from the abstract. If the information you're looking for is not in the abstract, we may not be able to extract it for you. Elicit typically has access to open-access papers.

You can always upload your own PDFs or import PDFs from your Zotero library in the Extract workflow. In that case, we can use information from the full text of the paper, assuming it can be parsed.
