Notes: The variables are defined in Table 1. Table reports marginal probit estimates. Tested positive takes value 1 if the subject was tested positive during the pregnancy and 0 if HIV-negative. Standard errors in brackets clustered at the visit date level.
**, * and + indicate statistical significance at the 1, 5 and 10 percent level respectively.
