The primary objective will be to compare readers' attention of shorter versus longer abstracts. The secondary objective will be to assess the perception of an abstract based on four indicators of a well-written abstract: (a) Informativeness, (b) Accuracy, (c) Attractiveness, and (d) Conciseness.\n\nThe study will involve researchers from all over the world who recently published an SR, regardless of their research field. To identify eligible authors, a search of MEDLINE (via PubMed) was conducted on May 5, 2024, for systematic reviews published between January 1, 2024, and March 26, 2024. A total of at least 6200 SRs will be selected from PubMed and assessed for eligibility.

When searching PubMed, researchers are initially presented with an overview of the references identified. After clicking on the title, the corresponding abstract appears. For full-text access, researchers must actively follow a separate link to the journal page.\n\nIn this RCT, participants will be randomly assigned in a 1:1 ratio to two groups (those receiving a long abstract vs. those receiving a short abstract). Both groups receive the same cover letter by e-mail explaining the purpose of the study, the use of the data, measures to ensure anonymity of participation, and a link for participation.\n\nThe link will direct participants to SoSci Survey, an online survey tool. Those in the group receiving the long abstract will see an abstract with a length of 771 words (PMID: 37955353). Those in the group receiving the short abstract will see an abstract with a length of 277 words (PMID: 37942649). Both abstracts are structured and pertain to the same review entitled "Percutaneous nephrolithotomy vs. retrograde intrarenal surgery for renal stones". This review was published once in the Cochrane Database of Systematic Reviews and once in the journal BJU International.\n\nThe design of the abstract presented is similar to that of PubMed, but no title or authors will be indicated. After reading the abstract, participants must actively click the "Continue" button to proceed with the survey.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'healthyVolunteers': True, 'eligibilityCriteria': 'The corresponding authors of systematic reviews that were indexed in PubMed between January 1, 2024, and March 26, 2024, and for which an English abstract is available will be included.
