An event for overall survival is death due to any cause. Survival time is defined as time from randomization to the date of death or last known follow-up (censored).

Five-year rate is reported simply as summary data; it is not the outcome measure.","dispersionType":"95% Confidence Interval","groups":[{"description":"Intensity-modulated radiotherapy (IMRT) with concurrent cisplatin\n\nCisplatin: 100 mg/m2 IV on days 1 and 22 of IMRT\n\nIMRT: 35 fractions over 6 weeks, 6 fractions per week, 2 Gray per fraction to total dose of 70 Gy.","id":"OG000","title":"IMRT + Cisplatin"},{"description":"Intensity-modulated radiotherapy (IMRT) with concurrent cetuximab\n\nCetuximab: 400 mg/m2 IV 5-7 days before IMRT then 250 mg/m2 IV weekly for 7 weeks\n\nIMRT: 35 fractions over 6 weeks, 6 fractions per week, 2 Gray per fraction to total dose of 70 Gy.","id":"OG001","title":"IMRT + Cetuximab"}],"paramType":"NUMBER","populationDescription":"Eligible participants.
