  1. a Measured in units of natural log transformed median fluorescence intensity (lnMFI). The “Mean” is the arithmetic mean, “SD” is the standard deviation, and “Difference” is equal to the mean of the cases minus the mean of the controls
  2. b MCV = Merkel cell polyomavirus
  3. c VP1 = the primary structural protein of human polyomaviruses
  4. d ST-Ag = the small T-antigen of human polyomaviruses
  5. e KIV = KI polyomavirus
  6. f WUV = WU polyomavirus
  7. g HPV = Human papillomavirus
