FIG. 1.

Box plot of HPV16, -18, and -52 DNA loads in GP5+/6+-PCR assay-negative (GP−)/SPF₁₀ assay-positive (SPF+) (light boxes) and GP5+/6+-PCR assay-positive (GP+)/SPF₁₀ assay-positive (dark boxes) samples. Viral load values are shown on the y axis as HPV copies/scrape specimen and are log transformed. For all three HPV types, the viral loads were significantly higher in the GP5+/6+-PCR assay-positive/SPF₁₀ assay-positive samples than in the GP5+/6+-PCR assay-negative/SPF₁₀ assay-positive samples (ANOVA; P values were <0.001, <0.001, and 0.006 for HPV16, -18, and -52, respectively). The upper and lower boundaries of the boxes represent the 75th and 25th percentiles, respectively. The thick black line represents the median, the whiskers represent the minimum and maximum values, and the asterisks represent outliers.
