Notes: Mean = The mean response below the toxic threshold.
A = The maximum stimulatory response.
B = Width of the stimulatory response (calculated from the lowest to the highest concentration showing a response that is 110% of the control response).
C = Distance from the concentration of the maximum stimulatory response to the ZEP.
ZEP = Zero equivalence point; The highest dose at which the response is equal to the control response.
BMD10 = The dose at which the response is estimated to have decreased 10% below control value.
Experimental laboratory replications conducted by Guo et al. (2011).
