Problem
Marcus et al (2014) article, "Is the Dodo bird endangered in the 21st century? A meta-analysis of treatment comparison studies"
Using above article, can we argue that the Dodo Bird Verdict/hypothesis (treatment equivalency), states no treatment is superior to the other rather they all are equally equivalent? vs There are specific therapies that are more effective than others for particular diagnoses ( CBT more effective for primary outcomes... ( measures of the symptoms/problems being treated))
How can this argument further be explained while being supported by Marcus et al (2014) article and other resources?
