2scents: SIDS deaths in the United States have been declining since the early 1990s for a variety of factors that include recommended changes in sleeping position and environment, clarification of the case definition, and diagnostic coding shifts [19–22].

You need to read carefully to understand what is being written here. “clarification of the case definition, and diagnostic coding shifts” basically means they changed the name of SIDS, so of course the rate of SIDS went down.
As I posted previously:
In 1992, to address the unacceptable SIDS rate, the American Academy of Pediatrics initiated a ‘Back to Sleep’ campaign, convincing parents to place their infants supine, rather than prone, during sleep.
From 1992 to 2001, the postneonatal SIDS rate dropped by an average annual rate of 8.6%. However, other causes of sudden unexpected infant death (SUID) increased.
For example, the postneonatal mortality rate from ‘suffocation in bed’ (ICD-9 code E913.0) increased during this same period at an average annual rate of 11.2%.
(In Australia, Mitchell et al. observed that when the SIDS rate decreased, deaths attributed to asphyxia increased. Overpeck et al. and others, reported similar observations.)
This results in a non-significant decline in SIDS
