| Population | People diagnosed with cancer of the oral cavity (ICD-O C01-C02, C03, C04, C05-C06) or oropharynx (ICD-O C09, C10); primary squamous cell carcinoma, histological variants of SCC and carcinoma in situ; head and neck cancer trials included if data available separately or at least 50% of participants had oral cavity or oropharyngeal cancer | Adults with squamous cell carcinoma of the oral cavity or oropharynx; 2488 participants across 12 studies (12% (298) oral cavity, 59% (1468) oropharynx, 29% larynx/hypopharynx, less than 1% other sites) |

| Comparison | Standard therapy (chemotherapy, radiotherapy, surgery or a combination) alone | Standard therapy alone: radiotherapy, chemoradiotherapy or surgery (n=1244); placebo plus standard therapy (n=293) |
| Outcomes | Overall survival/total mortality; Locoregional control; Disease-free survival; Progression-free survival or time to recurrence; Harms associated with treatment (adverse events); Quality of life; Direct and indirect costs to participants and health services; Participant satisfaction | Overall survival (n=1421); Locoregional control (n=424); Disease-free survival (n=261); Progression-free survival (n=1315); Adverse events (n=2400); Quality of life (n=424) |
| Study designs | Randomised controlled trials with a minimum follow-up period of six months | Randomised controlled trials, phase I to III (n=12) |
| Timing | Minimum follow-up period of six months | Minimum follow-up of at least 6 months; follow-up 24 to 70 months (monoclonal antibodies and immunotherapy) and 40 to 60 months (tyrosine kinase inhibitors) |
