Fits to the BED OD data for a single seroconverting mother from the ZVITAMBO Trial.

<p>Predicted values obtained from: A. LMM. Linear regression of the square root of OD values against log time (<i>t</i>) since the last HIV negative test (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049661#pone.0049661.e031" target="_blank">Equation (7</a>)). B. NLMM (U). Fitting the non-linear function given by <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049661#pone.0049661.e034" target="_blank">Equation (8</a>) to the untransformed BED OD data. C. NLMM (L). Fitting the non-linear function given by <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049661#pone.0049661.e036" target="_blank">Equation (9</a>) to the log-transformed BED OD data. D. Using the fit described in C, but now plotting log_e(OD) on the ordinate.
