Both cases and controls could have been diagnosed with autism, but it should have been a relative minority. Autism is relatively rare compared to a 314 diagnosis. This issue was added to the study limitations in the revised manuscript. “In the present study, neurodevelopmental diagnoses other than 314.xx were not examined among cases and controls. This limitation of the present study should have had a limited impact on the results observed because of the rarity of other neurodevelopmental diagnoses as compared to a 314.xx diagnosis, but future studies could further evaluate this phenomenon.” Comment 3.
In the exposed and control groups were there other related diseases such as Autism? If so, how many and what would happen to the analysis if you removed them?
