Estimates of HPV16 copy number in 10 pair of samples with or without arbitrarily added A9 species types +.
Samples 1-10, individually mixed with 10 samples containing HPV52, HPV31, HPV31/51, HPV52/62, HPV33/73, HPV35/51/52, HPV31/39/83, HPV18/53/67, HPV51/52/59/61, HPV33/39/51/52/59, respectably
□. Samples 1-10, individually mixed with HPV-negative samples * Difference = log10 units (of sample with A9 types) minus log10 units (of sample with HPV-negative sample)
