The best results are shown in bold. Since there are only 3 subjects at the 48th month, the Rs are not applicable.
Key: ADAS-cog, Alzheimer’s disease assessment scale–cognitive subscale; CDR-GLOB, clinical dementia rating–global; CDR-SOB, clinical dementia rating–sum of boxes; MMSE, Mini-Mental State Examination; oRF-L1, oblique RF with the L1 norm constraint; oRF-L1-soft, oblique RF with L1 and soft split; Rs, Pearson’s correlation coefficients.
