Figure 1 Histograms for late loss for the paclitaxel-eluting and control bare-metal EXPRESS stent groups for in-stent (A), analysis segment (B), and maximal regional (C) late loss definitions. Paclitaxel-eluting-treated patients had less, but more heterogeneously distributed, late loss.

Figure 2 Patient count data for those with and without target lesion revascularization (TLR), dividing late loss into 0.2-mm increments: (A) in-stent, (B) analysis segment, (C) maximal regional late loss.

Figure 4 Cumulative frequency distribution cares for in-segment late loss versus target lesion revascularization (TLR) for reference vessel size <2.5, 2.5 to 3.0, and >3.0 mm. Prob = probability.
