In recent years, the number of randomized controlled trials using cohorts and routinely collected data (e.g., electronic health records, administrative databases, and health registries) has increased. Such trials can ease the challenges of conducting research and save cost and time. Accordingly, to standardize such trials and increase the transparency and completeness of research reports, an international panel of experts developed the CONSORT-ROUTINE (2021) reporting guideline. The reporting guideline was published in 2021 in the BMJ. To help understand and formally apply the reporting guideline and improve the overall quality of this type of study, the present paper introduced and interpreted the development process and reporting checklist of the CONSORT-ROUTINE.
Surrogate endpoints, defined as biomarkers or intermediate outcomes utilized in clinical trials to replace the ultimate targeted outcomes, have witnessed a growing prevalence in both clinical trials and drug-device approvals in recent years. To standardize the application and reporting of surrogate endpoints in clinical trial protocols and associated studies, relevant scholars published the SPIRIT-Surrogate and CONSORT-Surrogate reporting guidelines in the BMJ in July 2024. This article provides an interpretation of these guidelines in conjunction with published case studies, with the aim of offering references for domestic researchers, elevating the overall quality of related clinical trials, and eventually facilitating the enhancement of domestic healthcare level.
