Dementia-free (left panel) and overall (right panel) survival curves and their 95% confidence intervals for patients with PET images demonstrating patterns supporting and not supporting a diagnosis of a neurodegenerative disease (survival according to the National Health Data System, N = 403). The red dotted lines indicate the 3 years threshold of follow-up to respond to the primary and one secondary objectives. Numbers below the respective figures represent the number of patients under follow-up without any dementia (left panel) or alive (right panel) with a PET scan not in favor of a neurodegenerative pattern (first row) and in favor of a neurodegenerative pattern (second row)
