Details

The LUMBAR table captures data around the Lumbar Puncture procedure. The form is collected regularly throughout the study each time CSF is collected from participants.

LPNDRSN

The possible values for this variable have been harmonized to account for versions of the form that were used both in the original and extended phases of the PPMI study. “Other” in the extended version was recoded from 7 to 10 and a new 7 code was added to account for a possible value in the original version of the form.
