Notes: The indication rates with the variable scores (1–9) were used according to the AUC 2011; this reflects a gradual value of the related indication: (1–3) for inappropriate indications with score 1 indicating a “more inappropriate” indication than scores 2 and 3, (4–6) for uncertain indications with score 4 indicating a “more uncertain” indication than scores 5 and 6, and (7–9) for appropriate indications with score 7 indicating a “less appropriate” indication than score 8 and score 8 “less appropriate” than score 9.
