Abstract
Conducting randomised controlled trials (RCTs) in rare paediatric diseases is often impractical or prohibitively expensive. Observational data from longitudinal cohort studies, disease registries, and population-based databases exist for children and adolescents, but standard observational analyses are typically limited by bias. Target trial emulation methods can improve the quality of observational analysis, address common sources of bias, and help fill evidence gaps in paediatric clinical practice. Applying target trial emulation methods in paediatric research creates unique opportunities, but also poses specific challenges. Tailored approaches are needed to address issues with small sample size, treatment-effect heterogeneity, longitudinal follow-up, and missing data. This Review aims to outline key concepts, such as what causal inference and target trial emulation are, justify the use of target trial emulation methods in paediatric observational research, discuss approaches to emulating key elements of an RCT protocol, and highlight unique paediatric applications of target trial emulation.
期刊介绍:
The Lancet Child & Adolescent Health, an independent journal with a global perspective and strong clinical focus, presents influential original research, authoritative reviews, and insightful opinion pieces to promote the health of children from fetal development through young adulthood.
This journal invite submissions that will directly impact clinical practice or child health across the disciplines of general paediatrics, adolescent medicine, or child development, and across all paediatric subspecialties including (but not limited to) allergy and immunology, cardiology, critical care, endocrinology, fetal and neonatal medicine, gastroenterology, haematology, hepatology and nutrition, infectious diseases, neurology, oncology, psychiatry, respiratory medicine, and surgery.
Content includes articles, reviews, viewpoints, clinical pictures, comments, and correspondence, along with series and commissions aimed at driving positive change in clinical practice and health policy in child and adolescent health.
