Are you unable to engage with the full context of the situation? You repeatedly refer to the OP in your comments but there is a much larger context.
Simple logic, see if you can follow:
1. Sophie publishes flawed research (nitroglycerin for osteoporosis)
2. Sophie practices medicine and gives patients nitroglycerin for osteoporosis, with knowledge that her study is a lie. This causes harm to patients, because she knowingly gives them a therapy that doesn’t work. This is malpractice.
