Overall survival of (A) non–HPV-associated HNSCC and (B) HPV-associated OPSCC cases after 5 years stratified by smoking status (<10 pack-years vs. >10 pack-years) with associated 10-year OS and HRs. HRs indicate risk of death of cases when compared to controls with the same smoking status. CI = confidence interval; HNSCC = head and neck squamous cell carcinoma; HPV = human papillomavirus; HR = hazard ratio; OPSCC = oropharyngeal squamous cell carcinoma; OS = overall survival.
