PRG4 expression was also positively corelated with plaque burden volume ratio (wall volume divided by vessel volume inclusive of lumen and wall, r = 0.452, p = 0.003) and showed a negative trend with lipid rich necrotic core volume (LRNC Vol Prop: LRNC volume as a proportion of total wall volume, r = −0.268, p = 0.095), but these associations were not independent ( Figure 1 C and Table S1 ). 3.2.
