What were the independent variables?
What was the dependent variable? Visual Analogue Score (VAS) of each of the 10 recommendations.

The role of exercise therapy in the management of osteoarthritis of the hip or knee.
What was the sample size and how was it chosen? The sample size was chosen to answer a survey. The survey was made by 10 recommendations and each participant was asked to indicate how strongly they rated each recommendation, based not just on research evidence but also on all aspects related to their knowledge and clinical opinion.
What was the experimental design and use of control group? One way ANOVA variance analysis
Were the instruments of measurement shown to be reliable and valid? There was similarity between the SOR produced by this method and the traditional methodology (Shekelle et al. 1999) (reliability). The mean VAS for each recommendation increased with the traditional SOR, and therefore the ...
