=Stuttering modification therapy

Only one long-term efficacy study of a stuttering modification therapy program has been published in a peer-reviewed journal. This study concluded that the program "appears to be ineffective in producing durable improvements in stuttering behaviors."

Removing study since there is more than one study (see Laiho, Auli, and Klippi, Anu from International Journal of Language & Communication Disorders. Vol 42(3), May-Jun 2007) and to be consistent with other sections.
