Any other information on results incl. tables

The prediction was based on dataset comprised from the following descriptors: "effect LOEL"
Estimation method: Taking average value from the 5 nearest neighbours
Domain logical expression:Result: In Domain

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

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"

Parametric boundary:The target chemical should have a value of log Kow which is >= -2.14

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of log Kow which is <= 4.62
