Variability in BED HIV incidence estimates as a function of optical density cut-off (<i>C</i>).

<p>The coefficient of variation for BED HIV incidence estimates obtained using the ZVITAMBO baseline data, as a function of the pre-set optical density cut-off (<i>C</i>). Incidence calculated using <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049661#pone.0049661.e009" target="_blank">Equation (1</a>) with values of estimated by NLMM.
