β represents estimated regression coefficient, standing for the mean difference between the index and reference categories and standing for the average increase (decrease) in 2 scales of the SF-36 for each 1-unit increase for continuous variables; SE represents standard error
a Standardized regression coefficient; * P < 0.05
