A Unifying Theory for SIDS

Table 3

SIDS rate per 1000 live births increases with live-birth order, U.S. 1995–2004 [27] as compared to an infection vector model (r = 0.9966).

Live birth order	1	2	3	4	5	6 or more
SIDS rate per 1000 live births	0.491	0.691	0.816	1.033	1.199	1.294
Model Rate 2.5[1−0.9^(1+LBO)]	0.475	0.678	0.860	1.023	1.171	1.304
