|
Change in ADOS-2 CSS for Social Affect in the L. reuteri group compared to the placebo group. ADOS-2 is a semi-structured, standardized assessment that observes social interaction, communication, play, and restricted or repetitive behaviors across five modules tailored to age and language level. Higher scores indicate a higher level of autism-related behaviors. |
