Temporal trends in invasive cancer IRs by cancer site, sex, and
Appalachian status, United States, 2001–2011. Rates are per 100,000 and
age-adjusted to the 2000 US standard population. Percent change (PC) was used to
quantify the total percent change in rates from 2001 to 2011. Annual percent
change (APC) was used to quantify the change in rates during 2001 to 2011 and
was calculated using weighted least squares regression. Caret (^) denotes APC is
significantly different from zero (P < 0.05). Appalachia
includes select counties in Alabama, Georgia, Kentucky, Maryland, Mississippi,
New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, and
Virginia, and all counties in West Virginia. Non-Appalachia includes all
counties not in Appalachia.
