AIC: Akaike information criterion; BMDL: lower confidence limit of the benchmark dose; BMDU: upper confidence limit of the benchmark dose.
a
Calculated by PROAST, as BMDS does not yet provide BMDUs except for the two‐stage model.
b
AIC differs less than two units from lowest AIC.
c
Model with lowest AIC.
