What did ancient Egyptian physicians want to predict?

Sorting into the Three Categories of Ailment

"An ailment which I will treat" - used for injuries that most likely will be cured.

"An ailment with which I will contend" - used for difficult but not impossible cases. The doctor will try to treat the condition, but the outcome is uncertain.

"An ailment not to be treated" - the condition cannot be treated at all because the injury is thought to be incurable.
