The findings helped to establish the scope and limitations of the use of DNA profiling to supplement the use of conventional forms of sample typing. The results were presented in logarithmic form, showing the likelihood ratio for 257 Caucasians and 111 Afro-Caribbeans. Given the current reference databases, the authors conclude that the method's effectiveness is limited. They note the difficulty in achieving reliable information at the case submission stage and the problem of recording entries from mixed-race individuals. This method would probably be used only in a major investigation where any information could assist in strategic decisions. The authors predict that this technique would be only of limited use in discriminating Indo-Pakistani Asians from the two groups studied in the present experiment. 1 table, 2 figures, and 5 references
