Dear Editor,

We enjoyed reading Trocchia et al's[1] recently published TriNetX-based study of pediatric cystic fibrosis (CF) patients. The authors found significant associations between venous thromboembolism (VTE) and an increased risk of various gastrointestinal disorders. While TriNetX allows users to analyze large amounts of aggregate patient data,[2] there is a risk of research design oversights when utilizing the automated analysis tools on the platform.[3] In this letter, we analyze some potential limitations of the Trocchia et al study.
