Just some quick questions regarding the volunteer flow chart in the paper (sorry for those of you behind a subscription paywall). What do the authors mean when a patient was excluded for an abnormal MRI? Why were only 30/40 of the remaining participants' PET scan data analyzed? Was it due to sufficient power?
Some other random questions
The authors used a "t test" for continuous measures of data. What kind of t-test though? Since these are repeated measures over time, I have been told a dependent t-test is needed. Is that what was used? PROC MIXED in SAS has a parameter for "repeated" measures, so I would assume so but it's really not clear.
Very interesting paper, and I will hopefully be reading it in full shortly.
