FIG. 2.

Receiver operating curves, comparing koala anti-hsp60 and anti-hsp10 IgG assays as tests to predict (i) tubal occlusion alone (fibrous occlusion of one or more sites in one or both uteri or uterine tubes) and (ii) tubal occlusion without active inflammation (occluded inactive) among Chlamydia-infected koalas. Curves are generated from sensitivity and specificity values calculated for a range of arbitrary cutoff values. The best assays and cutoff points are those closest to the top left corner (high sensitivity and specificity). Anti-hsp IgG assays were more predictive of koalas with tubal occlusion without an active component of inflammation in the uFRT than of tubal occlusion alone. vs, versus.
