Medical reversals in primary health care: towards improved clinical decision-making and education of healthcare professionals

没有良好科学支持的医疗实践经常被逆转。这种现象被称为“医学逆转”。当新的研究发现一种既定的医疗实践不如最初声称的有效时，就会发生医学逆转。

Medical practices unsupported by good science are often reversed. This phenomenon has been described as a 'medical reversal'. A medical reversal occurs when newer research finds an established medical practice to be less effective than originally claimed.
