a
The distribution of ED visits by insurance status in each year 2006-2010 is different from the distribution of visits in 2005 (p<0.01 in all cases; pairwise tests). Chi-square tests also indicate that the distributions are jointly significantly different across years (p<0.01).
b
Visit rates reflect estimated ED visits in the 1000s.
