In the Chap. 10 the relationships between treatment modality and quality of life (qol) score levels were assessed using a chi-square test of the interaction matrix. Many high qol scores were in the hydrotherapy and physiotherapy treatments, and in the subgroup that received counseling the overall differences from other treatments were statistically significant at p < 0.0001. In this chapter, using the same data, we will try and test what levels of qol scores were significantly different from one another, and, thus, provide more details about differences in effects.
