Question Posted 06/06/17:
Very simple question. What is the definition of VISCODE "f"? I cannot find it in the data definition or protocols. I thought it might be "final" but none of these patients have any other visits. Is it "failed" screening? Thanks.

In ADNI-1, VISCODE="f" was used for screen failure.
