Intraclass correlation between DNA fragment size and colonization status. This analysis was used to identify DNA fragments in T-RFLP profiles of 16S rRNA genes that are correlated with colonization by S. aureus tst⁺. Each circle shows the number of samples in which the fragment occurred and how well the fragment was correlated to colonization status. We would expect some of the fragments (circles) to have a higher correlation value if they were indicative of colonization or to have a lower correlation if indicative of precluding colonization.
