Interpretive note

This figure summarizes a criterion-level qualitative formulation, not a standardized diagnostic test. The 0–3 scale is a visual representation of qualitative evidence strength only (0 = absent, 1 = mixed, 2 = moderate, 3 = strong). It is not a diagnostic score, probability estimate, or substitute for formal assessment.

Overall current formulation: ASD is the best-fitting developmental explanation.
B3 remained mixed and was not required for the overall pattern.
Major differential issues needing formal review: tic-spectrum phenomena, just-right / compulsive phenomena, attention regulation, and language-generation burden.
