The horizontal bar chart presents the distribution of child sex by maternal ART previous status (N = 4951) for the period December 17, 2009 – December 5, 2024. It categorizes children based on whether their mother's ART status was known (FALSE) or unknown (TRUE).    Among male children, 2003 had mothers with a known ART status, while 481 had mothers with an unknown ART status. Among female children, 1942 had mothers with a known ART status, whereas 525 had mothers with an unknown ART status. Overall, the majority of children had mothers with a known ART history, suggesting good ART documentation, but a notable proportion remains with unknown status, which may impact treatment outcomes and HIV prevention efforts.
