Question

Question Posted 02/25/20:
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.
