Any other information on results incl. tables

The prediction was based on dataset comprised from the following descriptors: LOEL
Estimation method: Taking average value from the 10 nearest neighbours
Domain logical expression:Result: In Domain

(("a" and "b" ) and ("c" and "d" ) )

Domain logical expression index: "a"

Similarity boundary:Target: C(=O)(O)c1cc(C(=O)OC)cc(N(=O)=O)c1
Threshold=50%,
Dice(Atom pairs)

Domain logical expression index: "b"

Referential boundary: The target chemical should be classified as High (Class III) by Toxic hazard classification by Cramer (with extension)

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of log Kow which is >= 0.851

Domain logical expression index: "d"

Parametric boundary:The target chemical should have a value of log Kow which is <= 2.15
