E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcomes will be the differences of the change of physician’s diagnostic confidence (incremental confidence) between Rounds 1-2 and 2-3. Assuming that FBB imaging will be superior to CSF biomarker results, incremental confidence between Rounds 1-2 will represent the advantage of FBB imaging over CSF biomarker results between Clinical Raters, and incremental confidence between Rounds 2-3 will represent the advantage of FBB imaging over CSF biomarker results within Clinical Raters. Physician’s confidence will be validated versus adverse cognitive outcomes (development of dementia and cognitive deterioration) after 1 and 2 years |
Gli Outcome primari verteranno sulle differenze nella variazione di confidenza diagnostica (confidenza incrementale) dei medici tra le fasi 1-2 e 2-3. Assumendo che i risultati al FBB Imaging siano superiori rispetto ai risultati dei biomarcatori nel CSF, la confidenza incrementale tra le fasi 1 e 2 rappresenterà la superiorità dei risultati del FBB Imaging sui biomarcatori nel CSF tra i Clinical Rater, e la confidenza incrementale tra le fasi 2 e 3 rappresenterà la superiorità dei risultati del FBB Imaging sui risultati dei biomarcatori nel CSF entro i Clinical Raters. La confidenza dei medici verrà confermata rispetto alla comparsa di esiti cognitivi avversi (sviluppo di demenza e deterioramento cognitivo) dopo 1 e 2 anni. |

E.5.2 | Secondary end point(s) |
Secondary outcomes will be (i) the predictivity of cognitive outcomes by FBB imaging. The predictivity of hippocampal volumetry, CSF biomarkers, and FBB imaging towards cognitive outcomes at 1 and 2 years will be studied. The predictivity of FBB imaging will be contrasted to predictivity of the other biomarkers; and (ii) the agreement of the local reading by nuclear medics among themselves and with the centralized reading, and (iii) the agreement between local and centralized assays of CSF Ab42, whenever available |
Gli Outcome secondari riguarderanno (i) la capacità predittiva di outcomes cognitivi del FBB imaging. Verrà studiata la predittività degli esiti cognitivi a 1 anno e a 2 anni della volumetria ippocampale, dei biomarcatori nel CSF e del FBB Imaging. La capacità predittiva del FBB Imaging sarà messa a confronto con quella degli altri biomarcatori; i risultati secondari riguarderanno inoltre (ii) l'accordo sulle letture locali dei medici nucleari e con la lettura centralizzata, e (iii) l'accordo tra le analisi locali e centrali del CSF Ab42, quando disponibili |
