The “Template for Intervention Description and Replication” (TIDieR) is a widely used reporting guideline designed to help researchers report essential details about their interventions in clinical trials. TIDieR is comprised of 12 items detailing why, what, who provided, how, where, when/how much, tailoring, and modifications of the experimental and comparator interventions.
When it comes to paediatric trials, high-quality reporting is crucial to ensure trial interventions are reproducible and their findings can be translated into clinical practice.
To further improve the transparency and quality of intervention reporting in paediatric trials, an international team developed TIDieR-Children and Adolescents (TIDieR-C). TIDieR-C has incorporated 13 Paediatric Considerations (PCs) – guidance specific to the unique elements of paediatric trials for each TIDieR item. Further, the team provided good reporting examples from paediatric trials to illustrate the original TIDieR items and new PCs.
TIDieR-C aims to support trialists in delivering comprehensive and transparent descriptions of their interventions. The standard has been published and is now available:
