Box and whisker plots of hepatitis B virus (HBV) load in 3 groups of mothers whose serum contained hepatitis B virus e antigen (HBeAg), antibody to hepatitis B virus e antigen (anti-HBe), or neither of these markers (e Neg). Boxes are middle quartiles, horizontal lines are medians, whiskers are ranges, and dots represent 10 anti-HBe–seropositive mothers whose serum contained >104 IU/mL HBV DNA. Thirty-three anti-HBe–seropositive mothers and 1 mother whose serum did not contain either marker did not have detectable HBV DNA (<50 IU/mL).
