Figure 3 Angiographic restenosis related to lesion length and reference vessel diameter. The p value was <0.05 comparing angiographic restenosis rates of reference vessel diameter/lesion length subgroups between radiation-treated (A) and placebo-treated (B) patients, except in the group of lesions <15 mm in length in vessels >3.0 mm in diameter.
