Figure 3. Cytokine Staining in HCQ-responders, HCQ+QC-responders, and Nonresponders.

(a) There was a significantly higher percentage of area stained for IL-17 in the HCQ+QC-responders compared to HCQ-responders and nonresponders (p<0.05). (b) There was no significant difference in percentage of area stained for IL-22 between the nonresponders and responders to antimalarials. The graphs show mean ± SEM. *p < 0.05.
