Advancing the reporting of mechanisms in implementation science: A guideline for reporting mediation analyses (AGReMA).

Well-conducted mediation analyses have the potential to move implementation science forward by better understanding how or why implementation strategies cause their effects on outcomes. The AGReMA statement provides authors with recommendations for reporting primary and secondary mediation analyses of randomized trials and observational studies. Improved reporting of studies that use mediation analyses could help produce publications that are complete, accurate, transparent, and reproducible.
