I am afraid that you are mistaken. You will note that they say: "Within FARS, we identified 7813 children aged 2 through 6 years who were vehicle occupants restrained in a child restraint system or a seat belt in a nondrivable passenger car, van, pickup truck, or sport-utility vehicle that was involved in a crash with at least 1 passenger fatality between 1998 and 2003. Of these 7813 children involved in fatal crashes, 1096 children (14%) were killed." You will then note that in Table 1 for "Overall" the Fatal rate is 1096 (identical to the number of children, the 14% above, that were killed). You will also note that if you add together the FARS and NASS CDS numbers you will get 9246, which is the total number of children aget 2-6 from both and also the sum of 1096 and 8150 from the "Overall" column on Table 1. now that I think about it, it doesn't even matter. If the same relative rates are fatal and non-fatal (separately) that still says that they are practically equivalent. Also, it says so in the paper...
