On the basis of the studies at hand, about 10 percent of SIDS deaths that occur within 1 month after DPT vaccination occur within 3 days of vaccination. If half of these, 5 percent, were caused by DPT, there would be only an even chance of detecting it in the pooled analysis. In his paper prepared for the committee, Walker (1990) estimated that about 20 percent of the 5,000 annual U.S. SIDS deaths occur within 2 weeks of immunization, so perhaps 40 percent, or 2,000, occur within 1 month. A 5 percent increase in this number, 100 cases per year, could go undetected in the data available.
It didn't specifically say which "studies," or maybe I'm not looking hard enough. Maybe the one by Walker in 1987? It has a link to that paper there.
