Box/whisker plots of mitochondrial DNA levels in AZT-exposed and AZT-unexposed placenta and umbilical cords.

<p>Box and whisker plots show mitochondrial DNA (mtDNA) levels in placentas of HIV-1 infected women and in umbilical cords of their infants according to exposure to antenatal AZT. The median mtDNA level was significantly higher in women exposed to AZT compared to women without AZT-exposure. Accordingly, the median mtDNA level was significantly higher in umbilical cords of infants exposed to AZT compared to infants without AZT-exposure.</p
