Factors associated with CTO revascularization in multivariable analysis. Variables associated with CTO revascularization are shown along the vertical axis. The strength of effect is shown along the horizontal axis with the vertical line demarcating an odds ratio (OR) of 1 (i.e., no association); estimates to the right (i.e., > 1) are associated with a greater likelihood of CTO revascularization, whereas those to the left (i.e., < 1) indicate a reduced likelihood of CTO revascularization. Each dot represents the point estimate of the effect of that variable in the model, whereas the line shows the 95% confidence interval (CI)
