Figure 1. Effect of chronic exchange transfusions (CET) on Pain and Health Care Utilization Outcomes Using Propensity Matching.

Figure 1.

Estimated effects of CET on pain outcomes after 1:1 propensity matching for age, genotype, WBC, and total neutrophil count. The coefficient marked with the horizontal line shows the estimated effect of CET on patient-reported outcome pain domains in the figure on the left (an increase in scores represent worse symptoms and a decrease in scores represent better symptoms in all domains except in Pain Impact where lower scores represent worse symptoms and higher scores represent better symptoms) and on hospital utilization in the figure on the right (a decrease represents an estimated decrease in utilization). The vertical line shows 95% confidence intervals of the estimated effect. *p=<0.05, **p=<0.001
