a
Joinpoint version 3.5.2, Bethesda, MD http://surveillance.cancer.gov/joinpoint/.
b
0 joinpoint model results are included for all groups analyzed and 1 joinpoint model results are included for those which a significant change in trend was indicated.
c
APC = Annual Percent Change in TB case counts.
d
CI = Confidence Interval.
e
Indicates the year in which a significant change in trend occurred.
*
The APC is significantly different from 0 at p<0.05. For the 1 joinpoint model, asterisks indicate which segment(s) had a significant APC. The Philippines, India and China did not have a significant APC result from either 0 or 1 joinpoint models.
