In summarizing what is known about the treatment of autism spectrum disorder, you should conclude that although not free of problems, have shown the most promise.

Weitlauf, A. S., McPheeters, M. L., Peters, B., Sathe, N., Travis, R., Aiello, R., ... & Warren, Z.

Explanation:

Though, continued improvements in methodologic rigor are needed to support the evidence found. The authors conclude that “Substantial scientific advances are needed to enhance our understanding of which interventions are most effective for specific children with ASD and to isolate elements or components of interventions most associated with effects” (Weitlauf et al, 2014)
