Figure 4. The relationship between significantly elevated serum cytokine levels and fever in H7N9-infected patients.

Correlation between body temperature and each of the significantly elevated cytokines: IFN-γ (A), TNF-α (B), IL-6 (C), IL-10 (D), and IP-10 (E) were analyzed. The solid line in each graph represents the trend line of correlation. Each dot represents one patient at one time point.
