Speech and language therapy
Always ask yourself if the interventions evaluated in fair comparisons are relevant.
For example, a fair comparison of the effects of an intervention conducted in a school setting with a multidisciplinary team on a daily basis, may not provide a reliable estimate of its effects and safety in other settings, or in the hands of less experienced practitioners.
REMEMBER: If the intervention available to you is sufficiently different from those in the research studies, the results may not apply to you.
