Hi, I'm interested in working with the ROSMAP data to look at factors affecting time to AD onset and time to death. I was wondering if there is any information about age at study entry? I see that the clinical data file has age at diagnosis of AD and age at death/age at last visit, but I was hoping to also have age at study entry as a sort of 'left-truncation time' for potential survival analysis. Is that information available anywhere here?
