The joinpoint analysis is used to find the best-fit line through several years of data. Line segments are joined at points called joinpoints. Each joinpoint denotes a statistically significant change in trend.
*The APC is significantly different to zero (p=0.05)
†The AAPC is significantly different to zero (p=0.05).
‡Age-adjusted.
AAPC, average annual percentage change; APC, annual percentage change.
