Pearson correlations between subscales, or the total score of the PRUNE, and the subscales of the SF-36 obtained at follow-up indicate that pain, sensory/motor (SM) symptoms and total scores were consistently moderately correlated with the SF-36 physical subscales or summary score. The sensory/motor symptoms subscale correlated most strongly with overall physical health status. The bolded scores in each column show where the stronger relationships existed. (Correlations who are significant at p<0.05 are noted as *, and those where p<0.01 are noted as **.)
