Weighted risk factors of the maternal HIV seroconversion during pregnancy, South Africa, 2011–2012 (Reduced multivariate model).

<p>*Adjusted for all listed covariates, total pregnancies including the index pregnancy, and the amount of support the mother reported receiving during pregnancy weighted to account for sampling design and non-response, and with variance estimation via Taylor series linearization to account for sampling design (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0125525#sec006" target="_blank">methods</a>). Other potential confounders of the effects listed in this table, including mother’s marital status, Socio-economic status, number of living children, maternal knowledge of modes of HIV transmission, whether the infant was born at home, in a hospital or clinic and birth weight of the baby in kilograms were assessed but did not change the reported effects by more than 10% from the full model (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0125525#pone.0125525.s003" target="_blank">S3 Table</a>) and therefore are not included in the final model presented above.</p><p>Weighted risk factors of the maternal HIV seroconversion during pregnancy, South Africa, 2011–2012 (Reduced multivariate model).
