Spontaneous elimination of hepatitis C virus infection: A retrospective study on demographic, clinical, and serological correlates

Figure 1 Serological reactivity to HCV encoded proteins with respect to virus type, the putative source and the outcome of infection. Grey indicates iv drug use and white indicates iv non-use. Mean values are indicated by x, medians by -, boxes show the interquartil range (central 50% of observations) and whiskers show the largest and lowest observed value (if not identified as outlier). By applying a regression model, an overall lower reactivity in patients with self-limited infection could be confirmed (P = 0.0012). Quantitative reactivity appears not to be affected by the outcome or the source of infection in patients with HCV types 2 or 3 (P = 0.9512).
