The studies
Each one takes a single question — who waits longest for an autism assessment, say — and answers it from the published record rather than from impression.
Reusing them
Quote them, chart them, put them in a consultation response. We would rather the figures were used than cited politely.
What it is not
A reading of published statistics rather than original study, and no substitute for talking to a clinician. Where sources disagree, we say so.
