Additional file 1 of Epidemiological and viral characteristics of undiagnosed HIV infections in Botswana

Additional file 1: Table S1 Demographic and behavioural factors associated with newly diagnosed HIV-1 infections (n = 601) compared to known HIV-cases (n = 2995) in Botswana. Figure S1. Differences in terminal branch lengths for three gene regions: A. Gag, B. Polymerase and C. Envelope genes of the HIV-1C virus. Incident cases (blue), new cases (yellow) and known cases (grey) are shown in each plot. The Student’s t test was used to generate the p-values: ns -not significant, *p < 0.05, **p < 0.01, ***p < 0.001. After Bonferroni’s correction, no statistical difference was observed in terminal branch lengths across the HIV genes.
