APC, Annual Percentage Change, represents the change in rate on a yearly basis. An APC of 0 would mean no change in the rate, represented by a horizontal line. Asterisk indicates APC is significantly different from zero (p<0.05).

Open circle indicates that a change in slope has occurred; associated p-value indicates the statistical significance associated with that change in slope
