See cause and effect. Just because a patient gets better while taking a certain treatment, it does not necessarily indicate that they got better because of the treatment. Oftentimes conditions, even in orthopedic medicine, get better with time naturally. If one is taking a treatment during this natural healing process, it may appear as if the treatment itself caused the patient to improve. However, this is a dangerous conclusion as the patient may have gotten better independent of any treatments rendered. Avoid jumping to this often erroneous conclusion.
