Pts is patients. PB is plaque burden. WT is wall thickness. WTI is wall thickness increase.
*: The average δYM-Time, δPB and WTI values were calculated using absolute values. c2 = 0 and D2 = 2 for all cases. Due to axial shrink applied to the 3D thin-layer model, some C-Shrink values in 3D thin-layer model were negative.
