Pre-diagnostic dynamic HPV16 IgG seropositivity and risk of oropharyngeal cancer: Methodologic issues

We thank Erfan Ayubi and Saeid Safiri for their comments on our manuscript, Pre-diagnostic dynamic HPV16 IgG seropositivity and risk of oropharyngeal cancer, published in Oral Oncology in October 2017. In particular, we appreciate their identification of a transcription error in the upper bound of the confidence interval for the adjusted odds ratio of seropositivity with years prior to diagnosis in the 0–2 years category. The reported result of OR = 85.2, CI = 13.7–68.5 should have been OR = 85.2, CI = 13.7–684.6.
