What would be the ramifications of switching from current treatment to the new one midway through the current treatment?
If this particular patient asks about this study, and I won't be at all surprised if they do because this is a major article in a major paper and they're pretty well informed about their condition, I would probably tell them that while it looks very compelling I don't want to do this incorrectly and right now the best evidence is the WHO guideline as currently followed. Without going into detail, this patient is already on two of the three meds as it is.
