Onset years for first significant declines in county-level proportions of late-stage diagnosis and Average APC over 1981-2007. For each ethnic group and county in Florida, two statistics were computed from the joinpoint regression models fitted to the time series of noise-filtered proportions of prostate cancer late-stage diagnosis: onset year for the first significant decline in the proportion of late-stage diagnosis (i.e. APC negative and significantly different from zero), and average annual percent change (AAPC). Shaded counties denote counties without significant decline or AAPC not significantly different from zero.
