Response to "More evidence is needed for the association between serum myasthenia gravis and adverse pregnancy, delivery and neonatal outcomes".

This document is a response to a letter regarding a study on the association between serum myasthenia gravis (MG) and adverse pregnancy, delivery, and neonatal outcomes. The authors address the concerns raised in the letter and clarify their methodology. They explain that they used a directed acyclic graph (DAG) to guide their selection of confounders and followed STROBE guidelines. They also discuss the distinction between etiological research and prediction research, and state that their study aimed to investigate causal associations. The authors agree that maternal use of MG medications may influence neonatal outcomes, but note that this was not the focus of their research. They conclude by acknowledging the importance of medication use and stating that their next paper will explore this topic in more detail. [Extracted from the article]
