Relative income loss is expressed as the cost of productivity loss due to work absenteeism as a percentage of annual income. This is among patients who returned to work following surgery and reported their annual income in the survey.
Adjusted for age, gender, years of education, type of employment (full or part-time), ethnicity, had submitted claim related to medical problem, pain level at non-surgical sites, type of surgery
Single category comprises patients divorced, separated, widowed, or single
Note: The dependent variable is a function of the variable RTW (weeks) and thus it was not included in the multivariate analysis
