text: Yo, check it out, I got a study to drop,
  Talkin' 'bout seroreversion, don't you stop.
  We focused on infants, HIV-exposed but clean,
  Tryna find out what these babies mean.
  
  Early and late seroreversion, that's what we explore,
  Lookin' at the clinical traits, what's in store?
  Using ELISA, we measured the time,
  Mean duration was 50.1 weeks, pretty prime.
  
  Standard deviation was 14.8, that's the spread,
  Around 11.6 months, that's what we said.
  The range was wide, from 17.9 to 82.0 weeks,
  Antibodies disappearing, no peaks.
  
  For Western blot, the mean time was greater,
  68.3 weeks, man, that's the data.
  Around 15.8 months, that's the duration,
  Range from 44.9 to 94.1, no hesitation.
  
  Initial HIV titer, measured by cord blood OD,
  Had a significant relation, let it be.
  To the mean time of seroreversion, that's the key,
  Closely linked, as you can see.
  
  Gestation age, immunoglobulin, or CD4 count,
  No impact on seroreversion, that's the amount.
  Maternal booze, infantile issues, no connection,
  No effect on time, no need for correction.
  
  The lengthy seroreversion, it's clear, my friend,
  CDC's definition, it's accurate, no pretend.
  Positive ELISAs need Western blot's embrace,
  But only after 18 months, in the right case.
