TABLE 2.

Developmental milestone achievement and assistive device use. Summary description of developmental milestone achievement and the assistive device use for patients for whom these data were available in this dataset. Developmental milestones: The total number of patients recorded as able and which patients were able to achieve each milestone are listed. The number of patients who were unable to achieve milestones (i.e., a specific comment was made that the patient had not achieved the milestone, and the patient never achieved the milestone within available data) is also given. For those noted as able, the average age at which the milestone was first noted and the standard error are included, as well as sex. Assistive device use: Total number and specific patients using assistive devices (motor or communication) are noted.
