They were also asked to record their symptom improvement on a scale where 1 is equal to no improvement and 5 is equal to complete improvement. Ordinate in A: mean score on the pain journal. Ordinate in B: mean symptom improvement as recorded in the pain journal. Abscissa for both: scores from week 1 to week 6. Error bars represent the standard error of the mean (SEM)
