Figure 2. Wall thickness progression in thin and thick artery wall sectors, as assessed by IVUS at baseline, stratified for the presence and absence of NIRS signal.

Yellow: NIRS-positive sectors (NIRS [+]); red: NIRS-negative sectors (NIRS [−]); thin (plaque-free) <0.5 mm wall thickness by IVUS; thick ≥0.5 mm wall thickness by IVUS. * p<0.001.
