Notes: The percentage of patients who received OAK treatments, both current and recent, is given in relation to OAK severity. The effectiveness of the current treatments and respondent satisfaction were measured on a scale of 1–7 (where 1 was “not at all effective/satisfied” and 7 was “extremely effective/satisfied”) and expressed as a percentage of patients with each opinion.
Wilcoxon rank sum test, all groups P<0.0001.
