Table 6.

Predicted disease counts with rates, and amplitude at the beginning (T_start), breakpoint (T_break) and end (T_end) for each of two time periods

Years T_start–T_end	Data source^a	Predicted annual counts (rates per 100 000)^b			Amplitude
Years T_start–T_end	Data source^a	T_start	T_break	T_end	T_start	T_break	T_end
1993–2015	CDC	1174 (0.452)	1670 (0.578)	5925 (1.843)	11.769	2.627	3.482
1998–2006	CDC	1107 (0.401)	1620 (0.561)	2852 (0.956)	2.082	3.068	4.054
1998–2006	CMS	1142 (3.298)	462 (1.294)	970 (2.610)	1.034	1.552	2.070

CDC data include the entire population and CMS data only older adults (65+).

To estimate reporting rates per 100 000, the total US population was used for CDC rates, and the population of older adults (65+) was used for CMS rates.
