Details

The CLCKDRAW CRF was added to PPMI 1.0 in the 14-15 amendment (version date 02/01/2019). The version in PPMI 2.0 is largely similar, with the major differences being the variable descriptions. The descriptions were edited to be more clear and concise, but the variable meanings have not changed.

The CLCKDRAW CRF is closely linked to the MOCA table. In the MOCA, participants are asked to draw a clock that follows a certain set of rules (see MOCA for more details on the instructions). The clock drawn in the MOCA is the same clock that is analyzed by the investigator in this CLCKDRAW CRF.

CLCKTOT

Each question on the CLCKDRAW CRF is worth one point, with seven total points possible. CLCKTOT will be null if any of the variables in the sum are null.
