Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The 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. The corresponding author information will be extracted from all included SRs and randomized in a 1:1 ratio.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In 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.
The 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.
The 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.
