Table 5-4 Comparison of compounds present on the skin which are observed to be 

 relatively increased from one host with respect to the other. Compounds which 

 decrease markedly after an eight hour period from the more attractive host are also 

 reported. This table is categorically divided into five sections. A significant change 

 reflects a relative difference or change by a factor of 5 or greater between hosts, or 

 between host emanations and emanations detected after 8 hours. A slight change 

 refers to compounds with a relative difference of a factor range of 2-5.
