~-D <br />Figure 1 -Age-Adjusted Incidence Rates 1990-2003 <br />Orange County and North Carolina <br />Five-year (1999-2003) incidence rates were also computed and the results were similar to those found <br />for the period 1990-2003. None of these rates were found to be significantly higher than North Carolina <br />rates3.Trends in cancer incidence rates were also examined for all cancers combined. Trends in age- <br />adjusted rates for all cancers combined are presented in Figure 2 below. There does not appear to be <br />a temporal pattern in the rates. <br />Figure 2 -Age-Adjusted Incidence Rates by Year <br />All Cancers Combined, Orange County and North Carolina <br />soo - <br />500 <br />°0 400 - --- <br />0 <br />0 <br />`m 300 - - ----- --- <br />a <br />~ -- <br />200 - <br />--+-Qrange <br />100 -ta-North Carolina <br />0 <br />~9 ~~ ~9 ~9 ^9 ~9 ~9 ~9 ~~ ~9 ti~ ti~ ti~ ti~ <br />Year <br />95"/" confidence interv:ils mere calculated For the age adjusted incidence rates, using the method described in Fa}' IVIP, Feuer EJ <br />Confidence intervals Eor directl}' standardized rates: r1 method based on the Gamma distribution Statistics in IVfedicine <br />1997;16:791-807 <br />Page 38 of 47 <br />
