Hello,
I’m Seong-jin Son who is studying at the Centerfor Neuroscience Imaging Research in Korea.
To check the demographic information of theparticipant in the ADNI database, I was looking into PTDEMOG.csv and I have aquestion for you.
The 'PTTLANG' and 'PTPLANG' fields in the'PTDEMOG.csv' file are understood to mean 'Language to be used for testing theParticipant' and 'Participant's Primary Language', respectively.
But I can't find the label and its meaninganywhere in each field.
Please notice me the meaning of the labelsin the 'PTTLANG' and 'PTPLANG' fields.
Thank you.
Please refer to the data dictionary, which can be obtained via DOWNLOAD-->Study Data-->Study Info-->Data &Database in the ADNI repository
