Figure 4.

Proportion of oral antibiotics prescribed for different types of infections during the early enrollment period within the autism spectrum disorder (ASD) cohort and general population with no ASD diagnosis (POP) cohort, and within their subcohorts describing children with and without a gastrointestinal (GI) symptom diagnosed during the late enrollment period (+GI and −no GI subcohorts, respectively). The sum of proportions within each cohort/sub cohort may be greater than unity due to the occasional diagnosis of multiple infection types in one medical claim.
