Statistical methods / analysis
The rate of post-surgical pain following knee joint replacement surgery is estimated to range between 7-20%. One hundred participants will be recruited for this pilot study as 7-20 events will allow for assessment of the univariate relationships between baseline predictors and presence of post-surgical pain (eg, it is recommended that 10 'events' are needed for every predictor in the analysis). Univariate logistic regression (pain/no pain) and linear regression (intensity of pain) will be used to determine the relationship between a priori chosen variables and the presence of pain post-arthroplasty.
