Question

Question Posted 08/18/21:
Hi experts,I want to know how many subjects in ADNI1 have diagnostic information of 36 months or more. Because I want to screen out sMCI (stable within 3 years) subjects. However, I only found about 100 subjects based on ADNIMERGE.csv and DXSUM_PDXCONV_ADNIALL.csv , which accounted for only half of the data used by others. The reason is that some subjects do not have information 3 years or later and cannot judge whether they have changed ,such as 018_S_0087
. Please help me find more comprehensive information about MCI subjects in ADNI1.
Thank you.
