Levels of complement factor 3 (C3); plotted values are nonlog for ease of comprehension.

<p>(A) Plasma C3 levels in dengue-infected individuals during the acute phase (3–8 days after the onset of symptoms) and in healthy subjects. (B) Paired C3 levels of DHF patients during the acute and convalescent phases of dengue infection. The mean of C3 levels for acute and convalescence were 1.0+0.5 and 1.4+0.3 respectively. The C3 levels were measured by ELISA. Values shown are means and standard deviations. The p-values of two-tailed t-tests on the log-transformed data are indicated above each analysis.
