A Preliminary Analysis to Study Time Trends in the Incidence of Cancer of the Larynx

Abstract

In this paper, a graphical analysis of the data on the incidences and mid year population in Scotland for 1960- 1989 is done to study the temporal variation. The incidence rates along with the 95% confidence limits for the mean incidences are calculated. The main conclusion is that while the incidence rates are higher in older people the increase over time is mainly a result of cohort effects.
