Year: 2024
Type: study-registration
Abstract: tudy aim This study aims to descriptively synthesize information from all peer-reviewed articles registered in INPLASY and published between June 2020 and May 2025, and to analyze how they differ from those registered in PROSPERO.To this end, we will compare these articles with a random sample of peer-reviewed articles registered in PROSPERO during the same period to pinpoint their similarities and differences.We will address the following focused questions: 1) How many peer-reviewed articles registered in INPLASY were published in indexed journals between July 2020 and May 2025? 2) What percentage of published studies in INPLASY updated the protocol status as 'completed and published'?3) What types of evidence synthesis studies in INPLASY have been published the most?4) What was the publication rate of INPLASY protocols during the period analyzed?5) What is the mean time from registration to publication of INPLASY protocols?6) Do evidence synthesis studies registered in INPLASY differ from those registered in PROSPERO?We will compare the following variables: journal impact factor; journal c a t e g o r y ; p u b l i s h e r ; c o u n t r y o f t h e corresponding author; source of funding; publisher peer-reviewed protocol; method used to cite the protocol; protocol status updated after the article publication; and the time interval between study registration and final publication.
