aThese two methodologies, PCR and IHC, were used to detect the presence of EBV and high-risk HPVs.
bThe total number of samples examined in this study is 102.

cHigh & Intermediate indicate the number of the samples of high and intermediate grade and their respective EBV/HPVs statuses and P value as follows: .0031 for EBV+/HPVs−, .0155 for EBV−/HPVs+ and .0002 for EBV−/HPVs−.
dIntermediate & Low show the number of the samples of intermediate and low grade with their respective EBV/HPVs ranks as well as P value: .0056 for EBV+/HPVs−, .0020 for EBV−/HPVs+ and .0001 for EBV−/HPVs−.
