Figure 2 Association of statin treatment with slower progression of aortic stenosis (AS) as shown by odds ratios and 95% confidence intervals <1 for criteria of progression. The odds ratios are indicated by the circles (for the overall population) and by squares (for patients with systematic follow-up [F-U] not motivated by symptomatic progression) with their 95% confidence interval (continuous and dashed line, respectively). Progression criteria are defined by median in the population for (top to bottom) mean gradient (Mean grad), peak transaortic velocity (Vmax), dimensionless index (Index), aortic valve area (AVA), and aortic valve area standardized to body surface area (AVA/BSA). The directions of the changes are indicated by the arrows: upward for increases, downward for decreases.
