Those questions that were left blank or had two simultaneous answers were considered invalid. In the case of questions 35–37, not answering was considered as having no comments or as being in agreement with the statement.

Figure 2. Results of question 35. The number of participants stating that the use of some drugs was restricted in their hospital (n = 76), number with no restriction at all or need to request permission in particular cases (i.e. off-label use or recently approved drugs) (n = 115).

Figure 3. Results of question 36. The number of participants who agree with the present classification or who would modify or add new subgroups to the three patient profiles proposed.
