PPMs of stable MCI compared to progressive MCI group trajectories. PPMs are shown for differences of trajectory slopes in a group of 108 sMCI compared to 92 pMCI subjects. Here, we focus on the contrast for steeper slopes in pMCI compared to sMCI. Columns depict PPMs of gray matter, white matter and CSF tissue maps respectively. Color bars denote parameter contrast values cTθ, i.e. slope in sMCI minus slope in pMCI. Because CSF shows growth, the sign of the contrast was reversed.
