These results occasionally differ from those discussed in the several summary chapters because in some cases, workgroups applied common test criteria to investigators' data resulting in a change in the qualitative conclusion. The symbols used in this Table were representing data insufficient to draw firm conclusions: this is distinct from the weak positive (pink) designation: o. ip. and der represent use of oral, intraperitoneal and dermal routes of exposure, respectively; 3, 5 and * represents studies which have yet to be reported.
