  1. Results for each ethnic group include the estimated value and 95% confidence interval for three parameters: joinpoint year, annual percent change (APC) for each of the three time segments, and average annual percent change (AAPC) computed over the entire time series. For the last two parameters, the symbol * denotes parameters significantly different from zero at α = 0.05.
