Figure 3. Macrophage migration inhibitory factor concentration in blood after 18 months in exhausted and nonexhausted patients. Total patient population is divided in exhausted versus nonexhausted based on 18-month exhaustion scores. White box represents the exhausted group; gray box represents the nonexhausted group. Bars represent 95% confidence intervals; boxes represent the 50% range of the variable and the thick line in the boxes is the median. Mann-Whitney U test was performed to test for differences between the two groups. N for the exhausted group was 92; N for the nonexhausted group was 89.
