Figure 1From: Increased incidence of traffic accidents in Toxoplasma-infected military drivers and protective effect RhD molecule revealed by a large-scale prospective cohort study Rates of traffic accidents in RhD-negative (crosses) and RhD-positive (circles) military drivers within 12–18 months of military service. The y-axis shows rate (probability) of traffic accidents for subjects with particular anti-Toxoplasma antibody titers. The figures indicate numbers of RhD-positive/RhD-negative subjects with particular anti-Toxoplasma antibody titers (x-axis).Back to article page
