Fig 2. Value semantic networks.

Keywords were identified using the Atlas.ti 6.0 software. The words were sorted according to the frequency of their appearance in the interviews. The cut-off point, which divides the set of words into high-frequency and low-frequency groups, was identified. Radial graphs explaining the frequency of appearance were created with MS Excel 2007. The upper left-hand side (I) shows the most relevant values that are consistently mentioned and discussed by the participants prior to the CME intervention on clinical ethics. The lower right-hand side (II) shows the most relevant values that are consistently mentioned and discussed by the participants following the CME intervention on clinical ethics.
