[Believe the guidelines?]

In recent years the guidelines (GL) have experienced increasing popularity, in parallel with positive economic consequences and the low time commitment for doctors. Time, however, has photographed a more complex reality. On the one hand, it brought out the diversity and difficulty of the GL problems (questionable methodology, conflict of interest, unreliability of scientific societies, risk of overdiagnosis and treatment), on the other hand it raised the need for better quality control of the Education. In any case, only the time will tell to us if and when we will be able to answer the LG question.
