Figure 2 Baseline Calcification and Substantial Change in Atheroma Burden

Mean baseline calcium index in subjects stratified according to degree of relative change in percentage atheroma volume (top) and mean ± 95% confidence interval baseline calcium index in subjects stratified according to whether they underwent substantial change (at least 5% change in percentage atheroma volume) or no substantial change (bottom). *p < 0.001 for comparison between groups.
