We wish to thank Liu and colleagues for their interest in our article on the incidence of pediatric Horner syndrome and risk of neuroblastoma.1 We assume that issues regarding our methodology stem from the inherent limitations of retrospective clinical studies. However, our methodology was both clearly described and consistent, and therefore does not affect the validity of our findings.
