Fig. 2. Marginal contribution of explanatory variables to the odds of inclusion on Candidate List.

The figure presents the point estimates of the odds ratio and the corresponding 95% confidence interval for all parameters included in the logit model where the likelihood of inclusion on the Candidate List is predicted by the toxicological properties of the substances as well as the economic and knowledge parameters. Chemicals listed in the Candidate List are compared to (a) all chemicals registered under the European chemical regulation Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH, n = 15,169), (b) chemicals listed on the SIN list (SIN, n = 874), and (c) chemicals listed on the PRIO list (PRIO, n = 856). Parameters with estimates to the left of the vertical line at 1 will typically be of lower value in the Candidate List as compared to the list with which it is compared, and vice versa.
