Observed versus predicted incidence by clinical stage of head and neck cancer, corrected for total decline in incidence (Corr-Pred), by sex, age group and tumor localization, in Belgium in 2020. (A) Predicted and observed clinical stage distribution for all patients in 2020. (B) Difference between observed and corrected-predicted incidence per clinical stage for all patients in 2020 and by time period. (C) Predicted and observed clinical stage distribution for males aged 80+ in 2020. (D) Difference between observed and corrected-predicted incidence per clinical stage for males aged 80+ in 2020 and by time period. Difference between predicted-corrected and observed incidence is significant if the 95% confidence interval (error bar) of the difference does not include zero.
