I overlooked this earlier but one of the autism experts in NH that I work with pointed out that a further misleading is that part of the numbers were gathered by reviewing medical records of kids who _could_ fit the DMI-4 classification for autism spectrum disorders even if they’d never been given an autism diagnosis; they didn’t even examine many of the kids, just their medical records.
