Patterns of adjusted HPV viral load (VL) at two-week intervals for individuals positive by line blot for HPV types 16, 18, 31, 33, and 35.

White cells and grey cells represent the absence and presence, respectively, of an HPV infection as determined by real-time PCR. The grey scale indicates ordinal categories of increasing adjusted HPV VL values (from light gray to dark gray). The adjusted HPV VL represents the log of 106 times the ratio of HPV copies to ERV-3 copies. Missing VL values are indicated by outlined cells. The blank lines represent 11 infections detected by line blot assay that were either not detected (10) or had missing data (1) by VL.
