Applicant's summary and conclusion

Interpretation of results:
Category 1 (skin sensitising) based on GHS criteria
Conclusions:
Prediction: POSITIVE, based on a positive prediction probability greater than 0.5, in the range 0.911-0.945.
The WoE prediction was based on the Global model and on the identification of chemotype alert of concern for skin senstitization, i.e. bond:CS_sulfide_SC.
Executive summary:

Prediction:  POSITIVE.
