P value is based on independent T-test value for mean age at diagnosis.
P value is based on P value based on Pearson’s chi -square test for age, year of diagnosis, ethnicity, stage at diagnosis.
P’ based on difference between OPC men and women.
P” based on difference between OCC men and women.
*Indicates that P value is significant (level of significance <0.05).
OPC- oropharyngeal cancers; OCC- oral cavity cancers.
