Figure 2

The relative abundance of encrustation at each stent portion (proximal loop/shaft body/distal loop) in each patient (A), and the average of each group (B). Height color bars demonstrate the percentage of encrustation volume at each portion, and the case with no bar displayed had no stent encrustation. The Friedman test with the Bonferroni correction was used for statistical analysis. *P < 0.05.
