Excluding FFPE samples based on amplified DNA concentrations likely reduces false-positive HPV58 genotype and HPV co-infection assignments. Concentrations of DNA amplified from all samples (A–B), as shown in Fig. 3, or FFPE samples only (C–D). Samples are color-coded by the number of HPV co-infections detected (A and C) or their assigned HPV58 genotype status (B and D). The gray lines indicate the average DNA concentration for HPV− archived DNA samples. The 2-nM threshold used to filter samples is indicated by red shading
