- Population
- People with primary squamous cell carcinoma of the oral cavity (ICD-O C01-C06) or oropharynx (ICD-O C09-C10); head and neck cancer trials eligible where more than 50% of participants had oral cavity or oropharyngeal cancer (or separate data available)

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
