Figure 2 Changes in stent volume between initial deployment and follow-up in the Palmaz-Schatz group and the RADIUS group. The Palmaz-Schatz stents did not change significantly. The RADIUS stents, however, increased an average of 23.6% in volume (*p < 0.001 vs. initial). Vertical bars are mean ± SD. p < 0.001 for the stent type-by-time interaction.
