Overall, the results show that associations are more quantitative than qualitative in that all treatment types are significantly less prescribed to less severe patients i. Recommendations for prevention and early intervention trials.

While substantial data exist indicating that amyloid 6. One of the first two therapies was prescribed to This area has been the topic of several recent studies aiming at identifying clinically relevant phenotypes or developing prognostic scores [ 1314 ].
If the aim is to prevent neurodegeneration, needs to be accumulated before it can soundly inform operational it may be reasonable to select individuals with positive amyloid PET decisions. USA ; Larsen S. In this large sample of COPD patients cared for by respiratory physicians, several approaches to factorial analysis were used in a step by step manner to identify associations between administered treatments on the one hand, and clinical subtypes on the other.
