PRISMA 2020

A revision of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement is an important event. The PRISMA 2020 statement has, like its predecessor (now re-referred to as PRISMA 2009), been published in multiple journals. This paper describes the changes that have been introduced in the new checklist [1]. However, in the June issue of JCE we also publish a detailed report describing the development process of the update. [2]
