Discussion
Forty of the 208 questionnaires were returned by the postal service as undeliverable (green) and with no forwarding address. Of the remaining 168 questionnaires, 114 (68%) were completed and returned (blue). 54 were apparently received and not returned (yellow).

Satisfied patients included groups who could receive treatment closer to home (blue), died satisfied of unrelated causes (brown), just had an interval between injections of more than a year (white), and felt that their disease improved (light aqua).

55 patients had discontinued treatment for reasons of dissatisfaction. 48 have not resumed treatment (orange). 7 who expressed dissatisfaction with the treatments have since come in for further injections in the ensuing 18 months. (light blue)
